Ipod Mini - Voltage regulator IC

[Parmin]

Hi all,

My Ipod mini died on the way to Bourke. I think my car charger is
bad and giving out over voltage.

When I open the Ipod, I saw that one of the IC was toasted.

The IC is roughly 30mm from the bottom left corner of the PCB.
I think the designator of the IC is U11 and I have a feeling that
it is a voltage regulator IC.

It is 5mm square with visible 16 pins, 4 pins on each sides.

Anybody know what is this IC? It is a shame to toss a $300 device
without giving it a fighting try.

Any input is appreciated.
