TPS2373: Inquiry about PoE multi-connection solutions

Part Number: TPS2373
Other Parts Discussed in Thread: PMP22477

Hello,

My customer is looking for a multi-connection solution that can deliver more than 100W of power over standard with PoE.

ex) PD#1 (802.3bt 70W) + PD#2 (802.3bt 70W) = Load 140W

Are there any solutions like this among TI products?

If you have any information about this solution, please share it.

Thanks,

JH

    Hi JH,

    Thanks for reaching out. We recommend two solutions for your application. Please see the information below and let me know if you have any further questions or concerns. 

    - Using power limiting circuit and mix the power at the output side. It can offer active power limiting function to avoid either PD has > 71.3-W input power, but it is high cost, large size. (You can search PMP22477 for the power sharing circuit). TPS2373-4 is recommended for this design.

    - Parallel two PDs together. The PDs normally can balance the power passively if the layout, cable condition, temperature, and other factors are similar. But this power balance is not guaranteed by active control.TPS2372-4 is recommended for this design.

     

    Best regards,
