  • RE: PMP20859: could TPS2378 achieve the Dual-Input Redundant PoE PD like that in PMP20859

    David Strasser
    David Strasser
    Zach, Yes, that is correct. The TPS2372 (and TPS2373) used in PMP20859 has built-in pulsed MPS, which save quite a few external components, plus it is rated for higher power. Thanks, David

    Part Number: PMP20859 I require a dual PoE input design, but no external 48V input, so do I just delete the components ringed below. Looks like I won't need the 48V input connector, 48V sense control and 2 off circuits to pull (PoE) PG low if external…
