TPS2373: High power POE solution recommendation

Part Number: TPS2373
Other Parts Discussed in Thread: TPS2372

Hi team,

My customer are working the 5G FR2 mmWave system (RU+AIP) and its power consumption, that spend a lot of power consumption on the AIP portion, around 100w ~120w of total system power.

Do you have recommendation PoE solution to support this kind of product? Thanks.

  • Hey Ben, 

    Since that is beyond .bt spec limit, they have to choose between a few options. 

    1. They could use 2x TPS2372 with a single RJ45 port in Beyond BT application

    2. They could do a dual PD and dual DCDC that combine at the output to deliver greater than 90W. Customer could combine 2xPMP22477 to achieve this. 

    3. They could do two PD ports combing to single DCDC and use somethin like PMP8861

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
