Hey Mark,

The TPS2378 is a stand alone PD rated for 25W of power.

The closest replacement is the TPS2379, but it has one additional pin that must be configured. This is the easiest / most direct swap.

In the 25W space, we have parts that have the PD and PWM controller: TPS23731, TPS23734, TPS23751, TPS23754, TPS23754-1, TPS23756.

Other standalone PD's that are higher power are the TPS2372 and TPS2373.

Hi Michael,

for TPS2379, only different on Pin 8 with TPS2378, But customer design need support 48V adapter and POE.

Is there any risk when both powers (POE+adapter)supply to UUT at no ADP detection of PD?

Mark
