  • RE: TPS2373: PoE reference design for a PCB with space limitation.

    Hi Samuel, For PoE PD input power less than 51W and isolated DC/DC design, TPS23730 is recommended in general. Compared with TPS2373, TPS23730 integrated PWM controller so it will be a singe chip solution. We have below reference designs may help PMP22477…

  • RE: TPS23731: POE DESIGN || DC ADAPTER PRIORITY REF DESIGN

    Hi Hemal, Thanks for reaching out. You can considering using TPS23731's reference circuit ( PMP22806 ) + PMP22477’s secondary oring circuit ( PMP22477 ). It will lower the PoE output voltage when 12-V adapter is added. Please see the heighted circuit…
