  RE: TPS23756: PCB review

  Hello Shuang Feng, I have some comments on the schematic: - the sync FET on the primary side has a 10k ohm resistor on the gate. The typical value is 10ohm, not 10K. This is probably causing a massive delay or completely inhibiting the FET to turning...

  RE: INA181: VREF impedance

  Thanks Ian, Understood. Am using the A2 version for 5V high side sensing. Also found the 500K Ref impedance buried in the text description. Would be useful if that was listed in the specifications. I settled on a TLV431A low power shunt reg with minimized...

  RE: TPS23756: TSPS23756 Output unstable and low efficiency

  Hi Vincent, 1. The voltage reference on the secondary side (D27) should be TLV431A (the low voltage variant)*** 2. How come you change the R9 resistor from 1k to 100ohm? Regards, Tom A.
