TI Team,
I was wondering if I could get your opinion on the following.
I currently have the TPS2376-H designed into my circuit using the evaluation board reference design. I've added ORing diodes to my design, and have bypassed the DC/DC converter portion of the evaluation.
My question is about using the TPS2378 as an alternative. As you know, this device has the APD feature, which allows an external DC/DC source to provide power. Here are my two queestions:
1. With the APD feature, I shouldn't have to use ORing diodes in my design, right?
2. Will the T2P work for passive PoE, or a non-type 2 injector?
3. What's the best way to implement the power good signal? Should we use the TPS pin?
Your advice is greatly appreciated.
