TPS2373: TPS2373 QUERY

Part Number: TPS2373

Tool/software:

1. We will be using POE TPS2373-4RGW chip for type 4 class 8 power requirement, Also we have a secondary inpiut requirement +48V DC IN if POE supply not available. Could you please review the diagram once and share your comments. Do we need to add any ORing circuit or protection circuits while consider both POE and secondary power inputs?

2. Also in the "TPS2373-4EVM-758 Evaluation Module User's Guide (Rev. B)" what is the purpose of ADPT pin?Do we need to add the same in our design also?

  • Hi Aditi,

    Thanks for reaching out!

    Could you share a schematic in pdf? The shared link could not be opened on my side.

    ADPT is used to turn off the ideal diode FETs to avoid PSE and adapter short. You may or may not need it depends on your adapter location/voltage, and your rectifier circuit structure.
