  • RE: TPS23753A: TPS23753A Transformer parameter design problem

    Hello, Please refer to this design: http://www.ti.com/tool/PMP8803 It is 12V / 1A using the TPS23753A. Please mark this thread as resolved if this answers your question. Regards, Michael Pahl

  • RE: TPS23753A: Please help to review the schematic diagram of TPS23753A，thanks a lot!

    Hi Yi, - CLS resistor should be 63.4ohms for class 3 - VDD-VSS capacitance must be <0.12uF for successful detection - Since you are using a 12V adapter, I recommend reading our OR-ing appnote ( www.ti.com/.../slva306a.pdf) & work through our flyback design…
