This design note provides complete circuit schematic, PCB, BOM and transformer information of the evaluation board. It also provide efficiency, transient response, output ripple and thermal data of the evaluation board.This design utilized NCP1568 and NCP51530 for the active clamp flyback topology. Active clamp flyback topology effectively recycles the leakage energy. Another feature of this topology is the ZVS operation of the power MOSFETS. Because of no leakage losses and ZVS operation, this topology is suited for high frequency operation which results in size reduction of the transformer. Hence Active clamp flyback topology is well suited for high power density sub 100 W power supplies.NCP1568D is a highly integrated DC−DC PWM controller designed to implement an active clamp flyback topology. It features adaptive frequency scheme which optimizes frequency of operation and hence the efficiency over all load and input voltages. The NCP1568 features a HV startup circuit.NCP51530 is a 700 V high side and low side driver with 2 A current drive capability for DC−DC power supplies and inverters. NCP51530 offers best in class propagation delay, low quiescent current and low switching current at high frequencies of operation. This device is tailored for highly efficient power supplies operating at high frequencies. NCP4308 is high performance driver tailored to control a synchronous rectification MOSFET in switch mode power supplies.FUSB3307 is a fully compliant, highly integrated USB Power Delivery (PD) power source controller that can control a DC−DC port power regulator or the opto−coupler in the secondary side of an AC−DC adapter.Key Features•PoE Compatible DC−DC Input V oltages (37 V – 57 V)•High Full Load and Average Efficiency•Low Standby Power•Very Low Ripple and Noise•High Frequency Operation up to 400 kHz •Thermal and OVP Protection•Adaptive Frequency Operation based on Input and Output Load Conditions•Adaptive ZVS Operation•Inherent SCP and OCP Protection•Board Dimensions: 2.23” x 1.34” x 0.58”SpecificationsOutput Voltage5, 9, 12, 15, 20 VRipple< 2%Nominal Current 3 A / 2.25 A @ 20 VMax Current 3 A / 2.25 A @ 20 VMin Current ZeroDeviceApplication Input Voltage Output Power Topology I/O IsolationNCP1568D NCP51530 NCP4308D FUSB3307 FDMS86255 FDMS86101PoE to USB−PDAdapter37 Vdc − 57 Vdc45 W Active ClampFlybackIsolatedEVAL BOARD USER’S MANUALFigure 1.

The device isinternally matched to 50Ω,and therefore does not need any external matching.The value of the input and output DC blocking capacitors C2and C3should not be more than 100pF for applications above 100 MHz. However, when the device is operated below 100 MHz,the capacitor value should be increased.The nominal value of the RF choke L1 is 100 nH. At the frequencies below 100 MHz this value should be increased. At frequencies above 1GHz, a lower value can be used to tune the output return loss. For optimal results, a good quality chip inductor or a wire-wound SMD type should be chosen.Both the RF choke and the 22nF supply decoupling capacitor C1 should be located as close as possible to the MMIC.The printed-circuit board (PCB)top ground plane,connected to pins 2,4and 5must be as close as possible to the MMIC, and ideally directly beneath it. When using via holes, use multiple via holes, located as close as possible to the MMIC.Figure 2 shows the PCB layout, used for the standard demonstration board.Fig 1.Typical application circuit.mgu436RF_OUTRF_IN C1L1C2C3GND2GND1V SV SRF inputRF output8.1Application examplesThe excellent wideband characteristics of the MMIC make it an ideal building block in IF amplifier such as LNBs (see Figure 3).Material = FR4;

The evaluation boards can be adjusted for different output voltages by changing R1 and R2. In addition, L1, D1, C3, and R3 may need to be adjusted and should be recalculated to ensure stable operation. The ADP1612/ADP1613 evaluation module operates inpulse-width modulation (PWM) current mode with up to 94% efficiency. The shunt-selectable switching frequency and PWM current-mode architecture allow for excellent transient response, easy noise filtering, and the use of small, cost-saving external inductors and capacitors. Other key features include a 33 nF soft start capacitor, undervoltage lockout (UVLO), thermal shutdown (TSD), and jumper selected enable. The evaluation module demonstrates the operation and performance of the ADP1612/ADP1613.This data sheet includes I/O descriptions, setup instructions, the schematic, and the PCB layout drawings for the ADP1612/ ADP1613 step-up converter evaluation module.

A | Page 3 of 8EVALUATION BOARD HARDWAREThe ADP1612/ADP1613 evaluation module is fully assembled and tested. The following sections describe the various connec-tors on the board, the proper evaluation setup, and the testing capabilities of the evaluation module.INPUT/OUTPUT CONNECTORSEN Test BusThe EN connector is used to enable/disable the converter via the EN pin. Use one of the following methods to enable the converter. Do not leave the EN pin floating. •Use a jumper to connect the top two pins of the EN test bus. This connects EN to VIN and enables the converter (see Figure 2).08527-003PLACE JUMPER HEREFigure 2. Enabled Jumper Position•Use a jumper to connect the bottom two pins of the EN test bus. This connects EN to GND and disables the converter (see Figure 3).08527-004PLACE JUMPER HEREFigure 3. Disabled Jumper Position•Alternatively, connect a voltage between VIN and GND to the center pin of the EN test bus for independent control of the EN pin voltage (see Figure 4).08527-005CONNECT EXTERNALDEVICE HEREFigure 4. EN Pin Direct Connection0 Ω Shunt FREQ (R4)This shunt selects the switching frequency via the FREQ pin. Several methods are available as follows. •Shunt the top pads of FREQ (R4) for 1.3 MHz operation (see Figure 5).08527-006PLACE SHUNT HEREFigure 5. 1.3 MHz Operation Shunt Position•Shunt the bottom pads of FREQ (R4) for 650 kHz operation (see Figure 6).08527-007PLACE SHUNT HEREFigure 6. 650 kHz Operation Shunt Position• If this shunt is left open, the part defaults to 650 kHz.VOUT Test BusThe output voltage at the VOUT test bus is set by the resistive voltage divider network, R1 and R2. A load can be attached to the VOUT test bus.VIN Test BusThe VIN test bus connects the positive input supply voltage to the VIN pin. Connect the power supply to this bus and keep the wires as short as possible to minimize the EMI transmission.GND Test BusThe GND test bus is the power ground connection for the part via the GND pin as well as the bypass capacitors. Connect ground connections from external equipment to this bus.SW Test PointThe SW test point is for measuring the switch node (SW pin) behavior and switching frequency.EVALUATION SETUPFollow these setup instructions to ensure proper operation of the ADP1612/ADP1613 evaluation module:1. Select the passive components for the bypass capacitance,desired output voltage, compensation, and start-up time, using the applications information from the ADP1612/ ADP1613 data sheet.2. Connect the input supply ground to GND.3. Connect the positive input supply to VIN.4. Connect the desired load between VOUT and GND. Themaximum continuous output current of the ADP1612/ ADP1613 is dependent upon the input and output conditions.5. Apply a voltage between 1.8 V and 5.5 V (ADP1612) or2.5 V and 5.5 V (ADP1613) to the VIN test bus.6. Move the jumper on the EN test bus to the enabled position.EVAL-ADP1612/ADP1613Rev. A | Page 4 of 8PERFORMANCE EVALUATIONThe following sections discuss tests and the resulting oscil-loscope waveforms. Oscilloscope waveforms and typical performance characteristics are provided in the ADP1612/ ADP1613 data sheet.Line RegulationThe line regulation is observed and measured by monitoring the output voltage (VOUT) while varying the input voltage (VIN).Load RegulationThe load regulation is observed and measured by monitoring the output voltage (VOUT) while sweeping the applied load between VOUT and GND. To minimize voltage drop, use short low resistance wires, especially for heavy loads.EfficiencyThe efficiency, η, is measured by comparing the input power to the output powerININ OUT OUT I V I V ××=ηLine TransientThe line transient performance is evaluated by generating a high speed voltage transient on the input (VIN) and observing the behavior of the evaluation module at the inductor (SW) and the output (VOUT.)Load TransientThe load transient performance is evaluated by generating a fast current transient on the output (VOUT) and observing the behavior of the evaluation module at the inductor (SW) and the output (VOUT.)Oscillator FrequencyThe oscillator frequency can be measured by connecting an oscilloscope to the SW pin.Inductor CurrentThe inductor current is made accessible by removing one side of the inductor from its pad and connecting a current loop in series. Place an oscilloscope current probe on the loop to view the current waveform.EVAL-ADP1612/ADP1613Rev. A | Page 5 of 8EVALUATION BOARD SCHEMATIC AND LAYOUT08527-008Figure 7. ADP1612/ADP1613Boost Application Evaluation Board Schematic08527-00908527-01Figure 9. ADP1612/ADP1613 Boost Application PCB Bottom LayerLAYOUT GUIDELINESFor high efficiency, good regulation, and stability, a well-designed printed circuit board (PCB) layout is essential. Use the following guidelines when designing PCBs:•Keep the low ESR input capacitor, C IN (labeled as C7 in Figure 8), close to VIN and GND. This minimizes noise injected into the part from board parasitic inductance. •Keep the high current path from C IN (labeled as C7 in Figure 8) through the L1 inductor to SW and GND as short as possible.•Keep the high current path from VIN through L1, the rectifier (D1), and the output capacitor, C OUT (labeled as C4 in Figure 8), as short as possible.• Keep high current traces as short and as wide as possible. •Place the feedback resistors as close to FB as possible to prevent noise pickup. Connect the ground of the feedback network directly to an AGND plane to make a Kelvin connection to the GND pin.•Place the compensation components as close as possible to COMP . Connect the ground of the compensation network directly to an AGND plane that makes a Kelvin connection to the GND pin.•Connect the soft start capacitor, C SS (labeled as C1 in Figure 8), as close to the device as possible. Connect the ground of the soft start capacitor to an AGND plane that makes a Kelvin connection to the GND pin.•Avoid routing high impedance traces from the compensa-tion and feedback resistors near any node connected to SW or near the inductor to prevent radiated noise injection.EVAL-ADP1612/ADP1613Rev.

Logic DiagramM2716NMOS 16K (2K x 8) UV EPROM2048 x 8 ORGANIZATION525mW Max ACTIVE POWER, 132mW Max STANDBY POWER ACCESS TIME: –M2716-1 is 350ns –M2716 is 450nsSINGLE 5V SUPPLY VOLTAGE STATIC-NO CLOCKS REQUIREDINPUTS and OUTPUTS TTL COMPATIBLE DURING BOTH READ and PROGRAM MODESTHREE-STATE OUTPUT with TIED-OR-CAPABILITYEXTENDED TEMPERATURE RANGE PROGRAMMING VOLTAGE: 25V DESCRIPTIONThe M2716 is a 16,384 bit UV erasable and elec-trically programmable memory EPROM, ideally suited for applications where fast turn around and pattern experimentation are important require-ments.The M2716 is housed in a 24 pin Window Ceramic Frit-Seal Dual-in-Line package. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programmingprocedure.Table 1. Signal NamesJuly 19941/9查询M27128A-1F1供应商Figure 2. DIP Pin ConnectionsNote: Except for the rating "Operating Temperature Range", stresses above those listed in the T able "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the SGS-THOMSON SURE Program and other relevant quality documents.Table 2. Absolute Maximum RatingsDEVICE OPERATIONThe M2716 has 3 modes of operation in the normal system environment. These are shown in Table 3.Read Mode. The M2716 read operation requires that G = V IL , EP = V IL and that addresses A0-A10have been stabilized. Valid data will appear on the output pins after time t AVQV , t GLQV or t ELQV (see Switching Time Waveforms) depending on which is limiting.Deselect Mode . The M2716 is deselected by mak-ing G = V IH . This mode is independent of EP and the condition of the addresses. The outputs are Hi-Z when G = V IH . This allows tied-OR of 2 or more M2716’s for memory expansion.Standby Mode (Power Down). The M2716 may be powered down to the standby mode by making EP = V IH. This is independent of G and automat-ically puts the outputs in the Hi-Z state. The power is reduced to 25% (132 mW max) of the normal operating power. V CC and V PP must be maintained at 5V. Access time at power up remains either t AVQV or t ELQV (see Switching Time Waveforms).ProgrammingThe M2716 is shipped from SGS-THOMSON com-pletely erased. All bits will be at “1" level (output high) in this initial state and after any full erasure.Table 3 shows the 3 programming modes.Program Mode . The M2716 is programmed by introducing “0"s into the desired locations. This is done 8 bits (a byte) at a time. Any individual address,sequential addresses, or addresses chosen at ran-dom may be programmed. Any or all of the 8 bits associated with an address location may be pro-grammed with a single program pulse applied to the EP pin. All input voltage levels including the program pulse on chip enable are TTL compatible.The programming sequence is: with V PP = 25V, V CC = 5V, G = V IH and EP = V IL , an address is selected and the desired data word is applied to the output pins (V IL = “0" and V IH = ”1" for both address and data). After the address and data signals are stable the program pin is pulsed from V IL to V IH with apulse width between 45ms and 55ms. Multiple pulses are not needed but will not cause device damage. No pins should be left open. A high level (V IH or higher) must not be maintained longer than t PHPL (max) on the program pin during program-ming. M2716’s may be programmed in parallel in this mode.Program Verify Mode. The programming of the M2716 may be verified either one byte at a time during the programming (as shown in Figure 6) or by reading all of the bytes out at the end of the programming sequence. This can be done with V PP = 25V or 5V in either case. V PP must be at 5V for all operating modes and can be maintained at 25V for all programming modes.Program Inhibit Mode. The program inhibit mode allows several M2716’s to be programmed simul-taneously with different data for each one by con-trolling which ones receive the program pulse. All similar inputs of the M2716 may be paralleled. Pulsing the program pin(from V IL to V IH) will pro-gram a unit while inhibiting the program pulse to a unit will keep it from being programmed and keep-ing G = V IH will put its outputs in the Hi-Z state.ERASURE OPERATIONThe M2716 is erased by exposure to high intensity ultraviolet light through the transparent window. This exposure discharges the floating gate to its initial state through induced photo current. It is recommended that the M2716 be kept out of direct sunlight. The UV content of sunlight may cause a partial erasure of some bits in a relatively short period of time.An ultraviolet source of 2537 Å yielding a total integrated dosage of 15 watt-seconds/cm2 power rating is used. The M2716 to be erased should be placed 1 inch away from the lamp and no filters should be used.An erasure system should be calibrated peri-odically. The erasure time is increased by the square of the distance (if the distance is doubled the erasure time goes up by a factor of 4). Lamps lose intensity as they age, it is therefore important to periodically check that the UV system is in good order.This will ensure that the EPROMs are being com-pletely erased. Incomplete erasure will cause symptoms that can be misleading. Programmers, components, and system designs have been erro-neously suspected when incomplete erasure was the basic problem.DEVICE OPERATION (cont’d)Note: X = V IH or V IL.Table 3.

It features quick transient response using its Advanced Constant On-Time (ACOT TM) control architecture that provides stable operation with small ceramic output capacitors and without complicated external compensation, among other benefits. The input voltage range is from 4.5V to 18V and the output is adjustable from 0.765V to 8V. The proprietary ACOT TM control improves upon other fast response constant on-time architectures, achieving nearly constant switching frequency over line, load, and output voltage ranges. Since there is no internal clock, response to transients is nearly instantaneous and inductor current can ramp quickly to maintain output regulation without large bulk output capacitance. The RT7276 is stable with and optimized for ceramic output capacitors.With its internal 90mΩ switch and 60mΩ synchronous rectifier, the RT7276 displays excellent efficiency and good behavior across a range of applications, especially for low output voltages and low duty cycles. Cycle-by cycle current limit, input under-voltage lock-out, externally-adjustable soft-start, output under- and overvoltage protection, and thermal shutdown provide safe and smooth operation in all operating conditions.The RT7276 evaluation board uses the RT7276GQW IC in a WDFN-10L3x3 package with an exposed thermal pad. The IC is also available in a PTSSOP-14 package with an exposed thermal pad.Features●Fast Transient Response●Steady 700kHz Switching Frequency at PWM●3A Output Current●Advanced Constant On-Time (ACOT TM) Control●Optimized for Ceramic Output Capacitors● 4.5V to 18V Input Voltage Range●Internal 90mΩ Switch and 60mΩ Synchronous Rectifier●0.765V to 8V Adjustable Output Voltage●Externally-adjustable, Pre-biased Compatible Soft-Start●Cycle-by-Cycle Current Limit●Output Over- and Under-voltage Shut-downEvaluation BoardKey Performance Summary TableKey features Evaluation board number: PCB002_V1 Default Input voltage 12VMax Output Current 3ADefault Output Voltage 1.05VDefault Marking & Package Type RT7276GQW (WDFN-10L 3x3)Operation Frequency Steady 700kHz at PWMOther Key Features Advanced constant On-time(ACOT TM) controlPower GoodAdjustable Soft-start (external capacitor)PSM/ PWM Auto SwitchedProtection Over current protection:Cycle-by-Cycle Current LimitHiccup Mode Output Over- and Under-voltage Shut-downEvaluation Board Bench Test Setup ConditionsHeaders Description and PlacementPlease carefully inspect the EVB IC and external components, comparing them to thefollowing Bill of Materials, to ensure that all components are installed and undamaged.

Connect a jumper at JP1 terminals 1 and 2, connecting EN to GND, to disable operation.2. Apply a 12V nominal input power supply (4.5V < V IN < 18V) to the VIN and GND terminals.3. Set the jumper at JP1 to connect terminals 2 and 3, connecting EN to VIN through resistor R30, to enableoperation.4. Verify the output voltage (approximately 1.05V) between VOUT and GND.5. Connect an external load up to 3A to the VOUT and GND terminals and verify the output voltage and current.Output Voltage SettingSet the output voltage with the resistive divider (R23, R28) between VOUT and GND with the midpoint at FB. The output is set by the following formula:OUT R23V = 0.765 x (1 + )R28The installed V OUT capacitors (C11, C12) are 22μF, 16V X5R ceramic types. Do not exceed their operating voltage range and consider their voltage coefficient (capacitance vs. bias voltage) and ensure that the capacitance is sufficient to maintain stability and provide sufficient transient response for your application. Installing a small 5pF to 22pF capacitor at C30 (in parallel with R23) may be desirable to improve transient response for higher output voltages.

Evaluates: MAX16136MAX16136 Evaluation Kit General DescriptionThe MAX16136 evaluation kit (EV kit) is fully tested and assembled circuit that demonstrates the capabilities of the MAX16136, a high-precision reset IC offering window-threshold and window-watchdog monitoring. The MAX16136 EV kit is designed to facilitate the evaluation of various features of the MAX16136 such as input overvoltage/undervoltage faults, window-watchdog violation, and OV latching/unlatching capability. The MAX16136 EV kit operates over the automotive temperature range.The reset signal at RST asserts low when the voltage at IN falls outside of the overvoltage/undervoltage window-threshold settings. An overvoltage signal at OV latches low to indicate overvoltage condition at IN and a watchdog output signal at WDO pulses low when the signal period at WDI falls outside of the window-watchdog timing. The EV kit also features a push-button switch at CLR to unlatch the overvoltage fault output (OV ). Two indicators, OV_STATUS LED and UV_STATUS LED, provide visual fault status at the input for overvoltage and undervoltage conditions.Features● 3.3V Nominal Input Threshold Voltage●±4% Undervoltage/Overvoltage Thresholds withRespect to Nominal Input Threshold ●8ms(t WD_F )/80ms (t WD_S ) Window-WatchdogTimeout ●10ms Reset Timeout for RST signal ●Reset LED Indicator●Overvoltage Fault LED Indicator ●Clear Fault Input Push-Button Switch●-40°C to +125°C Operating Temperature Range ●Proven 2-Layer 2oz Copper PCB Layout ●Demonstrates Compact Solution Size ●Fully Assembled and Tested319-100457; Rev 0; 10/19Ordering Information appears at end of data sheet.Quick StartRequired Equipment●MAX16136 EV kit●DC power supplies: 3.5V/50mA and 5V/100mA ●One digital multimeter (DMM) ●Function generator ●Two-channel oscilloscopeProcedureThe EV kit is fully assembled and tested.

The EV kit is designed to monitor a 3.3V system supply within ±4% window threshold for undervoltage and overvoltage faults.The MAX16136 EV kit includes two LEDs, OV_STATUS and UV_STATUS, to indicate the undervoltage and overvotlage faults at the input (IN). OV_STATUS turns red when the input voltage goes above the overvoltage threshold indicating an overvoltage fault. OV_STATUS LED remains on even if the voltage at the input goes below the overvotlage threshold. To turn off OV_STATUS LED, pull CLR to ground (refer to the device data sheet’s electrical characteristics table for proper pulse-width duration on CLR). UV_STATUS indicates the state of reset output of the MAX16136. UV_STATUS turns blue when the input voltage goes either below the undervoltage threshold or above the overvoltage threshold and turns off after the reset timeout period once the input voltage is within the input’s window-threshold. To connect OV or RST to a voltage other than V DD, remove R1 and connect external voltage at V PULLUP.Undervoltage/Overvoltage Functionality●Slowly lower the 3.3V DC level at IN to about 3.168V(typ) and verify the UV_STATUS LED is turned on,indicating undervoltage fault. Bring the DC voltage at IN back to 3.3V while monitoring that UV_STATUSLED is turned off.●Slowly increase the 3.3V DC level at IN to about3.432V (typ). Verify that the OV_STATUS LED andUV_STATUS LEDs are both turned on due to anovervoltage fault. Bring the DC level at IN back to3.3V and verify that the UV_STATUS LED is turnedoff while OV_STATUS LED stays on, indicatinglatched output at OV. ●Press the push-button at CLR to unlatch overvoltageat OV and turn the OV_STATUS LED off.Note: See below calculation to accommodate IN accuracy and hysteresis for undervoltage and overvoltage thresholds. Window-Watchdog FunctionalityWhile monitoring both WDI and WDO on the scope slowly increase the frequency of the signal at WDI such that the period between two falling edges of the signal is shorter than 8ms. Verify the pulse duration at WDO is 50ms indicating fast watchdog timeout period violation. Slowly decrease the frequency of the signal at WDI such that the period between two falling edges is longer than 80ms. Verify the pulse duration at WDO is 100ms indicating slow watchdog timeout period violation.Overvoltage LatchThe open-drain output, OV latches low when the IN voltage exceeds the overvoltage threshold, the OV signal is latched to low, to clear the latch first make sure the input voltage is below the overvoltage threshold and then pull CLR low using the pushbutton switch.Status LEDThe MAX16136 EV kit features two status LED for RST and OV signal. 1KΩ pullup is connected to the LEDs to limit the sink current into the RST and OV pin. When IN voltage fall outside of nominal window voltage UV_STATUS LED will turn on showing the status of RST pin. OV_STATUS LED is used to indicate the status of OV pin, if IN voltage is more than overvoltage threshold OV_STATUS LED is turn on and latched to this state even IN voltage come back to its nominal voltage range. CLR push-button must be pressed to turn off the OV_STATUS LED. PULLUP VoltageThe MAX16136 EV kit provides the option to connect different voltage rail for RST, OV, WDO pullup resistor. Remove the 0Ω resistor (R1) from the EV kit and connect the desired pullup voltage to V PULLUP.Setting Input ThresholdsThe MAX16136 monitors a system supply voltage for undervoltage/overvoltage window-threshold. Depending on the system supply tolerance requirement, the undervoltage/ overvoltage thresholds can be factory-trimmed from ±4% to ±11%. The tolerance setting is symmetrical with respect to the selected nominal input threshold voltage. Below is a detailed calculation of how to determine the undervoltage/ overvoltage threshold levels with ±1% threshold accuracy for 3.3V ±4% supply voltage.V INNOM = 3.3VT OL = ± 4%V UVTH = V INNOM (1 − 4%) = 3.3V (1 − 0.04)= 3.3V − 0.132V = 3.168VV OVTH = V INNOM (1 + 4%) = 3.3V (1 + 0.04)= 3.3V + 0.132V = 3.432VWhere V INNOM is the selected nominal input threshold voltage, T OL is the input tolerance, V UVTH is undervoltage threshold voltage and V OVTH is the overvoltage threshold voltage.The MAX16136 monitors the supply voltage with ±1% accuracy over the operating temperature and supply range. The accuracy range for the 3.3V ±5% is shown below:V UVTH_A = V UVTH (1 ±1%) = 3.168V ± 0.03168VV OVTH_A = V OVTH (1 ±1%) = 3.432V ± 0.03432V Where V UVTH_A is the undervoltage threshold accuracy range and V OVTH_A is the overvoltage threshold accuracy.The MAX16136 also features input hysteresis that is factory programmable to either 0.25% or 0.50%. The hysteresis is calculated with respect to the nominal input voltage. For the 3.3V nominal input voltage and 0.25% hysteresis we have the following:V INNOM = 3.3V,HYS = 0.25%V HYS = V INNOM (0.25%) = 3.3V(0.0025) = 8.25mVIf the reset is due to an overvoltage event at the input, 8.25mV must be subtracted from the voltage point where the reset was triggered, as shown in Figure 1, where 8.25mV must be added in case of an undervoltage event, to bring the device out of reset at the end of reset timeout period.Figure 1: Graphical Description of Overvoltage Threshold#Denotes RoHSNote: Indicate that you are using the MAX16136 when contacting these component suppliers.SUPPLIERWEBSITELite ON WURTH ELECTRONICS PanasonicPARTTYPE MAX16136EVKIT#EV KitHYSTERESIS+1%-1%+4%3.3V3.397V3.432V 3.466V3.423V V OVTHV OVTH -HYSTERESISV INNOMt RPRESETOVBOrdering InformationComponent SuppliersMAX16136 EV Kit Bill of MaterialsITEMREF_DESQTYMFG PART #MANUFACTURER VALUEDESCRIPTION1C1, C22885012206071;CGJ3E2X7R1E104K080AA;C1608X7R1E104K080AA;C0603C104K3RAC;GRM188R71E104KA01;C1608X7R1E104K;06033C104KAT2A;CGA3E2X7R1E104K080AA;GCJ188R71E104KA12WURTH ELECTRONICS INC;TDK;TDK;KEMET;AVX;TDK;MURATA0.1UFCAPACITOR; SMT; 0603; CERAMIC;0.1uF; 25V;10%; X7R; ‐55degC to + 125degC; +/‐15% from ‐55degC to +125degC2CLR, GND, GND1‐GND3,IN, OV, RST, VDD,V_PULLUP, WDI, WDO 129020 BUSS WEICO WIREMAXIMPADEVK KIT PARTS; MAXIM PAD; WIRE;NATURAL; SOLID; WEICO WIRE;SOFT DRAWN BUS TYPE‐S; 20AWG 3CLR_SW 1EVQ‐Q2K03W PANASONIC EVQ‐Q2K03W SWITCH; SPST; SMT; 15V; 0.02A;LIGHT TOUCH SWITCH; RCOIL= OHM;RINSULATION= OHM; PANASONIC4MH1‐MH449032KEYSTONE9032MACHINE FABRICATED; ROUND‐THRU HOLE SPACER; NO THREAD; M3.5; 5/8IN; NYLON 5OV_STATUS 1LTST‐C190CKT LITE‐ON ELECTRONICS INC.LTST‐C190CKTDIODE; LED; STANDARD; RED; SMT (0603);PIV=5.0V; IF=0.04A; ‐55 DEGC TO +85 DEGC 6R11CRCW06030000Z0VISHAY DALERESISTOR; 0603; 0 OHM; 0%; JUMPER;0.1W; THICK FILM7R2, R32CRCW06031K00FK;ERJ‐3EKF1001VISHAY DALE;PANASONIC 1KRESISTOR; 0603; 1K; 1%; 100PPM; 0.10W;THICK FILM8R4, R6, R73CRCW060310K0FK;ERJ‐3EKF1002VISHAY DALE;PANASONIC 10KRESISTOR; 0603; 10K; 1%; 100PPM; 0.10W;THICK FILM9RST_STATUS1LTST‐C191TBKTLITE‐ON ELECTRONICS INCLTST‐C191TBKTDIODE; LED; ; SMT (0603); PIV=5V; IF=0.02A;BLUE10U11MAX1613600/VY+MAXIMMAX1613600/VY+EVKIT PART ‐ IC; MAX1613600/VY+T; CS04;HIGH‐PRECISION SUPERVISORY WITH WINDOWWATCHDOG AND OVERVOLTAGE INDICATOR;PACKAGE OUTLINE: 21‐100185; PACKAGE LAND PATTERN: 90‐100070; PACKAGE CODE: T822Y+3C11PCB 1MAX16136MAXIM PCB PCB:MAX1613612R5DNP0N/A N/AOPEN PACKAGE OUTLINE 0603 RESISTOR TOTAL29MAX16136 EV Kit SchematicMAX16136 EV Kit PCB Layout—Top MAX16136 EV Kit PCB Layout—BottomMAX16136 EV Kit PCB Layout—Top SilkscreenMAX16136 EV Kit PCB Layout—Bottom SilkscreenMAX16136 EV Kit PCB Layout DiagramsMaxim Integrated cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim Integrated product.

Supplied with the EvalAgSil are three bridge rectifier modules for evaluating the losses involved when using different rectifier technologies:∙Bridge Rectifier Module – featuring 2x DF01S bridge rectifiers∙Schottky Bridge Rectifier Module – featuring 8x SS36 Schottky rectifier diodes ∙Ideal Bridge Rectifier Module - featuring 2x FDMQ8205A MOSFET bridge rectifiersA simple method of utilising the most power output on a PoE system is to reduce the losses involved in the rectification. Rectification is required to enable the PD to be insensitive to the polarity of the power on the pairsets in a PoE system.Schottky rectifiers are an improvement over conventional bridge rectifiers due to their lower forward voltage drop, a greater improvement can be made by switching to an active bridge rectifier topology.The chosen bridge rectifier module should inserted into to EvalAgSil board using the two 2 pin and one 10 pin headers on the left hand side of the board before power is supplied to the board.Input SignatureThe EvalAgSil board will automatically direct the power from J101 through the bridge rectifier module to the input of the Silvertel module fitted into U1.This module will provide a 25K signature required to be powered from an IEEE compliant PSE.The EvalAgSil has been designed to be powered by any compliant IEEE802.3 PSE such as Silvert el’s Ag6120 PSE module.PSE DetectWhen U1 on the EvalAgSil board has been populated with a module that contains an ‘AT-DET’ feature, and it has detected it is being powered by an IEEE802.3 type 2 or greater PSE, the ‘at Flag’ pin will be pulled low, and this will cause LED3 to become illuminated on the EvalAgSil board.OutputThe output voltage will be present on both the DC10 connector, J4 and the banana plug terminals J3 and J5. J3 and the centre pin of J4 are the positive outputs, with the outer ring of J4 and J5 being the negative output.4.4.1Output AdjustBy default the nominal output voltage of the fitted module will be present on the output connectors. This can be adjusted up or down using the adjust connector, LK2.The EvalAgSil is fitted with two adjust resistors. The down adjust resistor R3, is fitted with a 68kΩ resistor. And the up adjust resistor R4, which is fitted with a 0Ω resistor. Depending on the module fitted the down adjust resistor, R3 may have to be replaced with a different value in order to provide the full down adjust stated in the corresponding datasheet.To increase the output voltage, insert a jumper to LK2 in the upper position, so that the link is between the middle and upper pin.To reduce the output voltage, insert a jumper to LK2 in the lower position, so that the link is between the middle and lower pin.If the output voltage needs to be set to a different value (within the adjustment range) then connect different value resistors in place of R3 (0Ω) or R4 (68K) and connect the jumper into the corresponding link setting.Note: ensure that the down adjust resistor is not shorted when connecting a module that has a higher stated resistance in the datasheet, as this could cause damage to the module.Data OutputAny data that is provided over the PI (Ethernet cable) connected to the Data & Power port, J100 will be transposed onto the Data output port, J101 via the data transformer.The data traces on the evaluation board have been designed to pass through10/100/1000/10GBASE-T Ethernet data signals. No processing or amplification of this signal will be performed on the evaluation board5 OperationTo ensure that the PSE does not apply power to a non-PoE enabled device the output port first checks for a valid PoE signature. If the PSE does not see a valid signature then it will disconnect, wait approximately 2 seconds then try again. Once a valid signature has been detected the PSE will then perform classification to determine the power requirement of the PD, only after this has occurred will the PSE supply power to the powered device.LED outputThere are three LEDs fitted to the EvalAgSil board, each of these can be disabled by removing the associated link jumper.EMIThe EvalAgSil contains many of the recommended components for preliminary EMI testing of an application.‘V’ capacitors, C2 & C3, can be enabled by inserting a jumper on to LK4.The board is fitted with ferrite beads, L1-6; if these are not required they can be effectively removed from the circuit by fitting R1 and R2 with 0 resistors.With some of the newer Silvertel module designs an additional EMI filtration method is to fit a 68nF capacitor to C4. Silvertel recommend that this capacitor is rated to 250V so that it retains more of the rated capacitance in the operating voltage range.6 Test SetupFigure 2 shows the basic set up using the EvalAgSil evaluation board powered bySilvert el’s E valAg6120 PSE.The equipment required: -EvalAgSil fitted with compatible Silvertel PD Sil Module.EvalAg6120 or other IEEE802.3 compliant PSEPower supply unit, +44-57V output e.g. 60V bench power supplyCAT5e or greater cablesApplication CircuitOptional equipment: -Data source e.g. PCFigure 2 Basic Test SetupData ThroughputTo pass data via the Evaluation boards, the data input (e.g. Internet) can be connected to J100 on the EvalAg6120 Board using a cat5e cable. The data is then passed through the data transformer, where power is added and sent out via connector J101 of theEvalAg6120 Board. The Data and power is extracted through J101 of the EvalAgSil board and then divided into its separate power and data through the data transformer. The data output is then available from J100 of the EvalAgSil Board, which can then be connected to the application device.7 Additional informationFull operating conditions and features of the Silvertel module set can be found in the relevant product datasheet, available from .8 Schematic9 Bill of Materials。
