Who dunnit?
It's a Fairchild synchronous switcher, actually a very nice part
electrically.

They did an eval board, but it didn't work (!) so they'll have to spin
it. So the sample is untestable.
I think we'll go with the National TSSOP-20 equivalent, with a single
power pad on the bottom. This Fairchild thing would be a nightmare to
rework.
I've started seeing a number of parts with multiple, funny-shaped
power pads on the bottom.

Ahhh...it's 0.65mm pitch. No big deal unless you've got a bad case of
presbyopia and can't even see 0.100" pitch parts and have to carry around an
effing magnifying glass everywhere you go and have started wearing reading
glasses and can't believe you're no longer twenty years old and get PISSED
OFF everytime you start to think about it!!!
