Copper, in a still air environment with T A =25°C. The Power dissipation P DSM is based on steady-state R θJA and the maximum allowed junction temperature of 150°C. The value in any givenapplication depends on the user's specific board design, and the maximum temperature of 175°C may be used if the PCB or heatsink allows it.B. The power dissipation P D is based on T J(MAX)=175°C, using junction-to-case thermal resistance, and is more useful in setting the upperdissipation limit for cases where additional heatsinking is used. It is used to determine the current rating, when this rating falls below the package limit.C: Repetitive rating, pulse width limited by junction temperature T J(MAX)=175°C.D.

DESCRIPTION Isolated μModule DC/DC Converterwith LDO RegulatorThe Demo Circuit 2358A is a 2kV AC isolated flyback μModule® DC/DC converter with LDO post regulator featur-ing the LTM8068. The demo circuit is designed for a 5.6V flyback output and a 5V post regulator output from a 4.5V to 40V input. The current capability of the 5.6V flyback output varies with input voltage from about 200mA at 4.5V IN to about 460mA at 40V IN. The current capability of the 5V LDO output is limited by either the current capabil-ity of V OUT1 minus V OUT1 loading or the 300mA current limit on the LDO post regulator itself. Figure 1 shows the maximum output current on V OUT1 when V OUT2 is notloaded, and V OUT2 when V OUT1 is unloaded. V OUT2 is the LDO post regulator from V OUT1.L, L T, L TC, L TM, Linear Technology, the Linear logo and µModule are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners. The two-stage converter provides an isolated flyback output as well as a low-noise LDO output. Figure 2 shows the output noise spectrum on the flyback output and Figure 3 shows the output noise spectrum on the LDO output. The LTM8068 data sheet gives complete description of the device, operation and application information. The data sheet must be read in conjunction with this quick start guide for demo circuit 2358A.Design files for this circuit board are available at /demo/DC2358ABOARD PHOTO1dc2358af2dc2358afPERFORMANCE SUMMARYPARAMETER CONDITIONSMINTYPMAX UNITSMinimum Input Voltage 4.5V Maximum Input Voltage 40V Output Voltage V OUT1 V IN = 4.5V to 40V 5.3 5.6 5.9V Output Voltage V OUT2V IN = 4.5V to 40V4.855 5.15V Voltage Ripple V OUT1V IN = 12V, I OUT1 = 200mA, I OUT2 = 0mA 25mV Voltage Ripple V OUT2V IN = 12V, I OUT1 = 0mA, I OUT2 = 200mA1mVDemo circuit 2358A is easy to set up to evaluate the per-formance of the LTM8068. Refer to Figure 4 for proper measurement equipment setup and follow the procedure below:NOTE: When measuring the input or output voltage ripple, care must be taken to avoid a long ground lead on the oscilloscope probe. Measure the input or output voltage ripple by touching the probe tip directly across the V IN and GND or V OUT and V OUTN terminals. See Figure 5 for proper scope probe technique.1. With power off, connect the input power supply to V IN and GND.2. Turn on the power at the input.NOTE. Make sure that the input voltage does notexceed 40V.3. Check for the proper output voltages. (For OUT1, check the voltage between V OUT1 and V OUTN . For OUT2, check the voltage between V OUT2 and V OUTN .) NOTE: If there is no output, temporarily disconnect the load to make sure that the load is not set too high.4. Once the proper output voltages are established, adjust the load within the operating range and observe the output voltage regulation, ripple voltage, efficiency and other parameters.QUICK START PROCEDURESpecifications are at T A = 25°CFigure 1.

The ‘Extended burst mode’ control greatly reduces the standby power consumption and helps the design easily to meet the international power conservation requirements.•Startup Current and Start up Control Startup current of OB2358 is designed to be very low so that VDD could be charged up above UVLO threshold level and device starts up quickly. A large value startup resistor can therefore be used to minimize the power loss yet achieve a reliable startup in application. For AC/DC adaptor with universal input range design, a 2 MΩ, 1/8 W startup resistor could be used together with a VDD capacitor to provide a fast startup and yet low power dissipation design solution.•Operating CurrentThe Operating current of OB2358 is low at 2mA. Good efficiency is achieved with OB2358 low operating current together with the ‘Extended burst mode’ control features.•Soft StartOB2358 features an internal 4ms soft start to soften the electrical stress occurring in the power supply during startup. It is activated during the power on sequence. As soon as VDD reaches UVLO(OFF), the peak current is gradually increased from nearly zero to the maximum level of 0.77V. Every restart up is followed by a soft start.•Frequency shuffling for EMI improvement The frequency Shuffling (switching frequency modulation) is implemented in OB2358. The oscillation frequency is modulated so that the tone energy is spread out. The spread spectrum minimizes the conduction band EMI and therefore eases the system design.•Extended Burst Mode OperationAt light load or zero load condition, most of the power dissipation in a switching mode power supply is from switching loss on the MOSFET, the core loss of the transformer and the loss on the snubber circuit. The magnitude of power loss is in proportion to the switching frequency. Lower switching frequency leads to the reduction on the power loss and thus conserves the energy. The switching frequency is internally adjusted at no load or light load condition. The switch frequency reduces at light/no load condition to improve the conversion efficiency. At light load or no load condition, the FB input drops below burst mode threshold level and device enters Burst Mode control. The Gate drive output switches only when VDD voltage drops below a preset level and FB input is active to output an on state. Otherwise the gate drive remains at off state to minimize the switching loss and reduces the standby power consumption to the greatest extend.The switching frequency control also eliminates the audio noise at any loading conditions.•Oscillator OperationThe switching frequency of OB2358 is internally fixed at 50KHZ. No external frequency setting components are required for PCB design simplification.•Current Sensing and Leading Edge Blanking Cycle-by-Cycle current limiting is offered in OB2358 current mode PWM control. The switch current is detected by a sense resistor into the sense pin. An internal leading edge blanking circuit chops off the sensed voltage spike at initial internal power MOSFET on state due to snubber diode reverse recovery and surge gate current of internal power MOSFET so that the external RC filtering on sense input is no longer needed. The current limiting comparator is disabled and cannot turn off the internal power MOSFET during the blanking period. The PWM duty cycle is determined by the current sense input voltage and the FB input voltage.•Internal Synchronized Slope Compensation Built-in slope compensation circuit adds voltage ramp onto the current sense input voltage for PWM generation. This greatly improves the close loop stability at CCM and prevents the sub-harmonic oscillation and thus reduces the output ripple voltage.•DriveThe internal power MOSFET in OB2358 is driven by a dedicated gate driver for power switch control. Too weak the gate drive strength results in higher conduction and switch loss of MOSFET while too strong gate drive results the compromise of EMI.A good tradeoff is achieved through thebuilt-in totem pole gate design with right output strength and dead time control. The low idle loss and good EMI system design is easier to achieve with this dedicated control scheme.In addition to the gate drive control scheme mentioned, the gate drive strength can also be adjusted externally by a resistor connected between VDD and VDDG, the falling edge of the Drain output can be well controlled. It provides great flexibility for system EMI design.•Protection ControlsGood power supply system reliability is achieved with its rich protection features including Cycle-by- Cycle current limiting (OCP), Over Load Protection (OLP) and over voltage clamp, Under Voltage Lockout on VDD (UVLO).With On-Bright Proprietary technology, the OCP is line voltage compensated to achieve constant output power limit over the universal input voltage range.At overload condition when FB input voltage exceeds power limit threshold value for more than TD_PL, control circuit reacts to shut down the switcher. Switcher restarts when VDD voltage drops below UVLO limit.VDD is supplied by transformer auxiliary winding output. It is clamped when VDD is higher than 30V. The output of OB2358 is shut down when VDD drops below UVLO_ON limit and Switcher enters power on start-up sequence thereafter.PACKAGE MECHANICAL DATA8-Pin Plastic DIPDimensions In Millimeters Dimensions In Inches SymbolMin Max Min MaxA 3.710 4.310 0.146 0.1700.500 0.020A1A2 3.200 3.600 0.126 0.142B 0.350 0.650 0.014 0.026B1 1.524 (BSC) 0.060 (BSC)C 0.204 0.360 0.008 0.014D 9.000 9.500 0.354 0.374E 6.200 6.600 0.244 0.260E1 7.320 7.920 0.288 0.312e 2.540 (BSC) 0.100 (BSC)L 3.000 3.600 0.118 0.142 E2 8.200 9.000 0.323 0.354IMPORTANT NOTICERIGHT TO MAKE CHANGESOn-Bright Electronics Corp. reserves the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice.
