Need help finding a substitute pwm controller

[The Performer]

Hi everyone, have an issue with a charger for an led work light that snap on tools no longer makes or can replace. The issue is inside of the charger it has an 8 pin controller that is starting to fail (I can spray canned air on it and the circuit works fine until the chip heats back up)

Anyway, the problem I am having is finding a replacement ic online. The part number on the IC is GW6203. From what I can gather is it is a proprietary ic made specifically by the chinese for this charger and no longer able to source a replacement.

Any help is greatly appreciated!

Actually I looked at the data sheet but didn't know that's what the "compatible with" meant.

Thank you very much buddy, found the rm6203 on ebay for a $.99

I've seen a number of these "exotic" Chinese PWM controllers before.
