looking for smps IC

[Luddite]

From a Dell 1504fp display power supply this IC feeds the primary side of
the transformer.
I cant find it listed anywhere going through all the permutations of its
markings.
anyone recognize it? http://pages.ripco.net/~a2k/junk/supply-ic.jpg

No, but found the pin spacing interesting/unusual.
