Tool/software:
A real odd on here-
Design is 30Vin to 15Vo. Load current ~8A max (for now). ~425kHz Fsw.
Load current is increased and at ~1-1.5A then the switching cycle starts to terminate early.
Sometimes the setpoint decreases to ~13.6V from 15V.
Trace 1: low drive, trace 2 high side drive, trace 4 load current in inductor 2A/div.
I thought the bump in low drive could potentially be causing the problem but I don't think that is it.
Another observation is that inductor never seems to carry a DC current- always ramps up and down from 0
but that is likely because of what is happening with the early termination.
