TPS23731: PoE daisy chain presentation

Hi Robert,

Thanks for reaching out.

I had shared you the PoE daisy chain file in email. It uses TPS2372 as the PD. TPS23731 (25.5W rated) has integrated PWM controller besides the PD controller, so it should be better if you have a local load. TPS2372 has a higher power rating (51W and 71W) but it is PD controller only.

May I know the detailed information below so we can look for suitable PSE and PD for you.

• What is your input power from PD and sending power from the PSE?
• Do you need to have a local isolated load or it is a pure pass through without power isolation?

Best regards,
