    Hi Rick,

    Thanks for reaching out.

    I will email you PoE daisy chain file which was verified on PD + PSE boards discretely. 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.

    Best regards,

    Diang
