TPS54560B-Q1: Schematic review

Part Number: TPS54560B-Q1

Hello,

My customer wants TI review of their TPS54560B-Q1 circuit design.

Could you please review the following circuit design?

  - The input voltage is planned to be 12V or 24V, and up to 36V can be input.

Thank you.

    Hi JH,

    The feedback resistor should be in parallel with SW pin, not in series with the inductor.

    Otherwise, the inductor is too small to me, recommend to use at least 7.2uH inductor. Also, if possible, you can recommend your customer to put 2 more capacitor at the output but only solder 3 as the original design, So they can debug easier if loop unstable.

    Regards
