I am looking for a pinout or datasheet for a chip labelled M51976FP. It
appears to be made by Mitsubishi, it's a SMPSU controller in a 20 pin
SOIC package.
I have the data on the M51977, which is similar (I think), but some pins
are clearly different.
Looking on datasheetarchiver and digchip didn't find anything. And a
google search (as ever) found plenty of people who sould sell me 100000
of them, but nothing else).
[It's uised in a PSU modile in an HP tape drive that I am working on, so
it does have som relevance to classic computers0.
Thanks in advance for any help
