The product which I am currently working on uses the LT4295 in a 71.3W PoE++ forward configuration, mostly inspired from the DC2584A EV Board.
I have used PoE injector which is is capable of supporting 802.3 af.
We have lowered the classification to type 3
My question is without PoE classification whether this circuit is expected to work. Because I am getting only 3.7V at the output of this circuit.
Attaching VPORT waveform and Primary Gate and Secondary Gate waveform. Switching frequency is matching
Are we missing anything here. Need your help to debug this issue and to proceed further.
