Can anybody ID a LED regulator chip JWB7J ?
« on: July 10, 2023, 01:33:09 am »
I'm reverse engineering an LED module, that apparently has a current regulator chip in a 6-pin SMT package, that bears
the label JWB7J.  I've tried to cross-reference this part with no luck.
Thanks much for any help!

JW is most likely for:

But, not sure about the B7J. You can search through LCSC by manufacturer and see if any of the photos show JWB7J. If not, well, at least you know which PNs aren't JWB7J.

Thanks a LOT!  I think this is the manufacturer, but they are REAL tight about their datasheets!  All you get is ONE page!
