Cannot find this 6 pin IC 362J38

I have a power brick I’m trying to repair but have been unable to locate a 6 pin IC 362J38 that I suspect is the issue. No other faults found except the fuse after going over the board 3 times. No visual clues. All e caps, mosfets removed & checked. Opto is good. Not sure what the IC function is, either pwm or a regulator, open to suggestion. It is located on the hot side. I’m trying to find out if there is a substitute IC – please answer only if you are familiar with these type of ‘cheap’ SMPS units. Just asking for help.

Zoom in on pic if you need more detail. After having a conversation with 2 qualified techs (far more experience with these than me) no other faults detected, it was suggested that an IC probably blew. The unit was accidentally shorted on the output side and stopped working. IC on secondary was replaced to no avail. Only other fault was fuse. Inductors were not tested.
