Hello Olivier,
It has been over a week since receiving a response from you. I am going to assume the matter is closed unless we hear back from you in the next 48 hours. Let us know if requiring anything further from us.
Thank you for considering PoE products…
I've looked into this issue quite a bit more and found out the following:
- When I am powering the unit just from an auxiliary power source, when the input power goes above 12.8 VDC, the TPS23750 is attempting to go into classification mode, hence…

Hi Steven,
Besides, TPS23750EVM-107 is a Buck-Converter Evaluation Board. TPS23750 and TPS23770 are similar chip mainly has UVLO difference.
I will take a look on its test report to find the clues.
