  • Hi,
    Just a wild guess could be the NCP5331 from ON-Semi. The NCP5331 is a “Two Phase CPU Controller with Integrated Gate Drivers for AMD’s Athlon Processor” and is packaged in a TQFP package. It has 4 gate drivers and it look like there is 4 similar circuits in the upper left corner on the die. The datasheet date is March 2005

No public wish lists :(
