Hello,
I have hard time identifying part value of my 8800GTXs memory power supply controller, which is marked as U501 on PCB (picture from the net):
Part code on my controller is AT-9E. All I could figure out about it, that it's a 2-phase buck converter controller, specifically designed for DDRx memory power supplies.
Similar purpose IC: https://www.richtek.com/assets/product_file/R … /DS8248A-05.pdf
I'd like to order it together with some additional parts, help!
