Hi guys
This IC is on a Zotax GTX780 3Gb
Normally I would find the datsheet by searching MPS OT Buck (a trick I learned here ) but that says it is a MPS8860 and it does not match the pinout of my chip which is a QFN with 6 leads on each side
It drives two 4901N dual MOSFET gates from pins 2, 17, 20 and 23 and these drive what looks like a 2 phase VRM which is probably VRAM. This rail does not power up.
Hopefully that is enough info to identify
Thanks
Rich
