Hi All,
Just some extra information which isnt in the previous post:
- Switching frequency of around 230KHz
- Original design did use VCCX but this has been disabled
- soft start time around 1 second
- hiccup timer 50ms
I have fitted some of the other FETs (IRFR4615PbF) to the PCB and left the rest as is. I can post some waveforms etc... of on open and light loads for reference if required?
again...ANY help is much appreciated.
