User's GuideSNVA082B–March2004–Revised May2013AN-1314LM5020Evaluation Board1IntroductionThe LM5020evaluation board is designed to provide the design engineer with a fully functional non-isolated flyback power converter to evaluate the LM5020controller.The performance of the evaluation board is as follows:•Input range:30V to75V(100V peak)•Output voltage:3.3V•Output current:0.2to4.5A•Measured efficiency:85%at1.5A,83%at4.5A•Board size:1.25×2.5×0.5inches•Load Regulation:1.5%•Line Regulation:0.1%•Line UVLO,Current LimitThe printed circuit board consists of2layers of2ounce copper on FR4material with a total thickness of0.050inches.Soldermask has been omitted from some areas to facilitate cooling.The unit is designed forcontinuous operation at rated load at<40°C with normal convection cooling.2Theory of OperationThe flyback converter is an inductive based converter in which inductive energy is stored by applying a voltage across an inductor in a similar manner to that of a boost converter.Here the similarity ends.Asecond coupled winding of the inductor transfers the energy to a secondary side rectifier after the voltage has been removed from the first winding.This allows the converter input and output grounds to beconfigured either isolated or non-isolated.There is also a voltage/current ratio change possible by altering the winding ratio between the first winding and the second winding.A semi-regulated auxiliary winding can also be provided.The flyback transformer is actually a coupled inductor with multiple windings wound on a single core.For simplification,we will refer to the first,driven winding,as the primary and the main output winding as the secondary winding of the flyback transformer.The transformer’s primary inductance is typically made as large as is practical.However,the airgapnecessary to store the cycle energy lowers the obtainable inductance.The higher the primary inductance, the less input ripple current will be generated and the less input filtering will be required.As shown,the LM5020directly drives a MOSFET switch to apply voltage across the primary.When the switch turns off,the secondary applies a forward current to the output rectifier and charges the outputcapacitor.In applications where the input voltage is considerably higher than the output voltage,the turns ratio between primary and secondary will reflect the input/output voltage ratio and the duty cycle.The LM5020is a full-featured controller providing an internal start-up regulator,soft start,over-current and under-voltage lockout.All

IncorporatedPowering and Loading Considerations Figure1.Simplified Flyback Converter3Powering and Loading ConsiderationsWhen applying power to the LM5020evaluation board certain precautions should be followed.TheLM5020evaluation board is quite forgiving of load and input power variations.The possibility of shipping damage or infant failure is always a concern at first power-up.4Proper ConnectionsBe sure to choose the correct wire size when attaching the source supply and the load.Monitor thecurrent into and out of the UUT.Monitor the voltages in and out directly at the terminals of the UUT.The voltage drop across the connecting wires will yield inaccurate measurements.For accurate efficiencymeasurements,these precautions are especially important.5Source PowerAt low input line voltage(30V)the input current will be approximately0.63A,while at high input linevoltage the input current will be approximately0.23.Therefore to fully test the LM5020evaluation board a DC power supply capable of at least75V and1A is required.The power supply must have adjustments for both voltage and current.An accurate readout of output current is desirable since the current is not subject to loss in the cables as voltage is.The power supply and cabling must present a low impedance to the UUT.Insufficient cabling or a high impedance power supply will cause droop during power supply application with the UUT inrush current.If large enough,this droop will cause a chattering condition upon power up.This chattering condition is an interaction with the UUT undervoltage lockout,the cabling impedance and the inrush current.6LoadingAn appropriate electronic load specified for operation down to2.0V is desirable.The maximum loadcurrent is specified as4.5A.Minimum load is specified at5%or0.23A.The resistance of a maximum load is0.73Ω(including cables).The resistance of a minimum load is14.4Ω.2AN-1314LM5020Evaluation Board SNVA082B–March2004–Revised May2013Submit Documentation FeedbackCopyright©2004–2013,Texas Instruments Incorporated Powering Up7Powering UpUsing the shutdown feature provided on the UUT will allow powering up the source supply initially with a low current level.It is suggested that the load be kept reasonably low during the first power up.Set the current limit of the source supply to provide about 1½times the wattage of the load.As you remove the connection from the shutdown pin to ground,immediately check for 3.3volts at the output.If more than a couple of seconds pass without seeing an output voltage,remove input power.A quick efficiency check is the best way to confirm that the UUT is operating properly.If something is amiss you can be reasonably sure that it will affect the efficiency adversely.Few parameters can beincorrect in a switching power supply without creating additional losses and potentially damaging heat.An efficiency above 80%is expected.After the unit is verified operationally,it can be powered up without use of the shutdown pin.8Typical Evaluation SetupFigure 2.Typical Evaluation Setup9Performance Characteristics 9.1Turn-on WaveformsWhen applying power to the LM5020evaluation board a certain sequence of events must occur.The soft-start feature allows for a minimal output voltage for a short time until the feedback loop can stabilize without overshoot.Figure 3,Figure 4,and Figure 5show typical turn-on waveforms at no load,5%load,and at full load.Input voltage,output voltage and output current are shown.Figure 6shows the initial ramp-up of the Vcc pin to 7.7volts through the internal regulator.The auxiliary winding starts to supply a higher voltage as the output voltage rises.The resulting second ramp is shown following the soft-start delay.This sequence is nearly identical for all loads and input voltages.Trace 1:Input Voltage,at 30VDC.Volts/div =20.0V Trace 2:Trace 1:Input Voltage,at 30VDC.Volts/div =20.0V Trace 2:Output Voltage,no load.Volts/div =2.0V Trace 3:Output Output Voltage,at

Select the filename from the File pulldown menu.MAX1464 Evaluation Kit 4_______________________________________________________________________________________Figure 1. Hardware Debugger WindowControl Program (MAX1464 Main.exe) The Control program includes functional buttons to have the MAX1464 perform a series of predefined lower level operations, such as reading the ADC, loading a file into flash memory, etc. The Control program can be used to perform a 2nd-order temperature compensation.The main purpose of the Control program is to provide the user with a tool to easily compensate a sensor. The compensation algorithm defined in Application Note 3649, MAX1464 Signal-Conditioner, Sensor Compensation Algorithm, has been implemented. All the user needs to do is to properly set up the EV kit/sensor and the environment condition for the sensor, and press the Read ADC and Characterize DAC buttons at each environment condition to fill the Data Array with valid data. Then by pressing three more buttons, the compen-sation coefficients are created and copied into the MAX1464 flash memory, creating a compensated sensor. Refer to the Control Program User Manual for a detailed description of each function/button and how to perform sensor compensation.Detailed Hardware DescriptionA complete set of hardware is included in the MAX1464EV kit package. A MAX1464 EV board, a MAX1464KEY, a 16-pin ribbon cable, a parallel-port extensioncable, and a few MAX1464 samples are included in theMAX1464 EV kit package. The MAX1464 EV kit board isdesigned to give the user the most flexibility and con-trol over the MAX1464. The user can use a fixed +5V oran +8V to +40V power supply to power up the EV kitboard. All critical pins are easily accessible. Twopotentiometers are provided to emulate a sensor outputand allow positive and negative input signals to theMAX1464, eliminating the need for an actual sensorwhile checking the functionality of the MAX1464. A smallarea with plated-through holes is intended to facilitatebuilding a small application circuit.

MAX17094 EV Kit Software Main WindowDetailed Description of HardwareThe MAX17094 EV kit contains a high-performance step-up switching regulator, a 250mA LDO, a positive two-stage charge pump, a negative single-stage charge pump, a high-speed op amp, and seven high-voltage level-shifting buffers for scan-driver applica-tions. The EV kit operates from a DC power supply between +1.8V and +5.5V that provides at least 2A.As configured, the step-up switching regulator (VMAIN)generates a +8V output and provides at least 300mA.The step-up switching-regulator output voltage can be adjusted up to +14V with different feedback resistors (see the Output-Voltage Selection section).The GON consists of two positive charge-pump stages to generate approximately +21.5V and provides up to 30mA. The GOF F consists of a single negative charge-pump stage to generate approximately -6.5V and provides up to 30mA. Loading GON and GOF F reduces the available VMAIN current proportionally.The op-amp output (VCOM) is SMBus programmable and is configured for a +2.4V to +4V output-voltage range. VCOM can source or sink peak current up to 150mA. The output-voltage range can be reconfigured to other voltages with voltage-divider resistors R16 and R17. Refer to the Setting the VCOM Adjustment Range section in the MAX17094 IC data sheet for more details.The seven logic-level to high-voltage level-shifting buffers can buffer seven logic inputs (A2–A8) and shift them to a desired level (Y2–Y8) to drive TF T LCD row logic. Each buffer outputs the voltage on the GOFF pin (set through JU1) when its respective input is logic-low.Each buffer (Y2–Y6) outputs the voltage-on GON1 (set through JU3) when its respective input is logic-high.Similarly, Y7 and Y8 output the voltage on GON2 (set through JU4).The seven switches within SW1 are used to select logic levels on A2–A8 for testing purposes. Set each switchopen when driving A2–A8 with external logic. Use jumpers JU14–JU18 to select between capacitive loads on outputs Y2–Y8 and YDCHG for testing purposes.GOFF Power Supply (JU1)The MAX17094 EV kit incorporates jumper JU1 to pro-vide an option to supply the gate-off (GOF F ) supply.GOF F can be supplied either through the on-board negative charge pump (VN) or with an externally applied voltage at the GOF F pad. See Table 1 for jumper JU1 configuration.Enable (JU2)The MAX17094 EV kit incorporates jumper JU2 to enable/disable the IC outputs. When EN is pulled low,the DC-DC converter and op amp are disabled. The high-voltage drivers and LDO will remain active if suffi-cient voltage is available for operation. See Table 2 for jumper JU2 configuration.GON1, GON2 Power Supply (JU3, JU4)The MAX17094 EV kit incorporates jumpers JU3 and JU4 to provide an option to supply the gate-on (GON1,GON2) supplies. GON1 and GON2 can be supplied either through the on-board positive charge pump (VP)or with an externally applied voltage at the respective GON_ pad. See Table 3 for jumpers JU3 and JU4 con-figuration.Evaluates: MAX17094MAX17094 Evaluation Kit_______________________________________________________________________________________5E v a l u a t e s : M A X 17094Level-Shifter Logic-Level Inputs(JU5–JU11)The MAX17094 level-shifter inputs can be supplied either using the on-board logic or from an externally applied signal through configuration of jumpers JU5–JU11. Additionally, when using on-board logic,SW1 controls the logic levels based on its own settings.When SW1 is on, the logic input is high. When SW1 is off, the logic input is pulled low through a 100k Ωpull-down resistor. See Table 4 for jumpers JU5–JU11 con-figuration.Level-Shifter Output Loading (JU14–JU21)The MAX17094 EV kit incorporates jumpers JU14–JU21to provide loading options at the level-shifter outputs,YDCHG and Y2–Y8. See Table 5 for jumpers JU14–JU21configuration.Output-Voltage SelectionThe MAX17094 EV kit’s step-up switching-regulator out-put (VMAIN) is set to +8V by feedback resistors R2 and R3. To generate output voltages other than +8V (up to +14V), select different external voltage-divider resis-tors, R2 and R3. Note that changing the VMAIN voltage setting changes the VN and VP charge-pump output voltages. Refer to the Main Step-Up Regulator and Output-Voltage Selection sections in the MAX17094 IC data sheet for more information.Detailed Description of SoftwareThe MAX17094 device includes a calibrator used for adjusting an LCD’s backplane voltage (VCOM) in TF T LCD displays. The VCOM voltage is adjusted by con-trolling the amount of sink current from a current source connected to the POS terminal of the op amp. This is accomplished by programming the desired setting into the device’s 7-bit internal DAC. The MAX17094 sup-ports four different I 2C slave addresses; configure SW2to select between different addresses. Refer to the MAX17094 IC data sheet for further details.Loading 7-Bit DAC SettingThe DAC setting corresponds to a certain sink-current level, which in turn corresponds to a specific VCOM voltage. With the MAX17094 EV kit software, the device’s 7-bit internal DAC is configured by entering an appropriate DAC setting into the Load DAC edit box.The DAC setting can be set from 0x00 (VCOM MIM ) to 0x7F (VCOM MAX ). The DAC setting is written to the device by pressing the Load DAC button (Figure 1).Reading 7-Bit DACThe MAX17094 7-bit DAC is read by either pressing the Read DAC button or by checking the DAC polling checkbox. When checked, the software continuously reads and displays the DAC’s current setting.Access Control RegisterThe Write To group box is used to select whether volatile (WR) or nonvolatile (IVR) memory is accessed during read and write cycles involving the data register.When the WR/IVR radio button is selected, data on the data register is written to both the WR and IVR. When the WR Only radio button is selected, data on the data register is written to the WR only.Simple SMBus CommandsThere are two methods for communicating with the MAX17094: through the MAX17094 EV kit software main window (F igure 1), or through the interface win-dow available by selecting the Action | Interface Diagnostic Window menu item from the menu bar. The Maxim command module interface window (F igure 2)includes a 2-wire interface tab that allows for execu-tion of the SMBusSendByte(), SMBusReceiveByte(),and SMBusQuick()commands. See Table 6 for details regarding SMBus commands.The Command byte and Data Out combo boxes accept numeric data in binary, decimal, or hexadeci-mal. Hexadecimal numbers should be prefixed by $ or 0x. Binary numbers must be exactly eight digits. See Figure 2 for an illustration of this tool.MAX17094 Evaluation Kit 6_______________________________________________________________________________________Evaluates: MAX17094MAX17094 Evaluation Kit_______________________________________________________________________________________7Figure 2.

General DescriptionThe DIODES™ AL8863 is a step-down DC-DC controller de-signed to drive LEDs with high output current. The device oper-ates at an input supply voltage from 4.5V to 60V. Series connec-tion of the LEDs provides identical LED currents resulting in uni-form brightness and eliminating the need for ballast resistors. The switching frequency range of AL8863 is from 50kHz to 1MHz. The wide operating frequency range allows more flexibility on compo-nent selection, and also with operating up to 1MHz, it allows the use of smaller size external components, hence minimizing the PCB size and driver board.The output current of AL8863 is set via an external resistor con-nected between the VIN and CSN input pins. Dimming is achieved by applying a PWM signal at the DIM input pin. The soft-start time can be adjusted using an external capacitor from the DIM pin to ground.The AL8863 is available in the thermally enhanced SO-8EP pack-age.
