20" iMac G5 iSight logic board help needed

[poobah]

Hi all!

I've got a 20" 2.1GHz iMac G5 iSight on my bench that doesn't power up.
I've tracked down the issue to a grenaded IC on the logic board.
The IC is an 8 pin SOIC chip, to the right of the power connector, just above the ALS connector. It is labeled UE300.

If you know what this guy is, can send me a good picture of one, or can provide me with the numbers from the IC, I can get this mac back to life.

Thanks!

UE300 is the silkscreen designator, not the chip number.

Judging by the location, adjacent traces and damage, I'd guess switching voltage regulator, but it could be anything.

If you go to apple and they tell you that you have to make a 500-700$ Logic board replacement better trash it! I had an issue with my iMac which needed one, it broke my heart, almost payed that, but if you think about it, even a Mac Mini which is cheaper than the repair cost is faster
