Hello, I’m having issues on a custom board design using the MP8017. What I’m experiencing is a brief period of time where the power is good under load and then it cuts off, some switch on and off pretty fast, others slower. I am looking for some help on what I should be looking at to determine what is causing this issue. Replacing the MP8017 with a new one fixes the issue, but I’ve had ones that are working fine fail after many hours, typically on a power cycle.
The specifications:
PoE Class 3
24V transformer output
Transformer MPN: 750311439
650khz
Output load ~2W
