Asus C231NA Chromebook schematic

[reformatt]

Need a schematic (or component identification) for a ASUS C231 Chromebook. Board is DA00Q7MB6E0 Rev E (Model 0Q7).

I've got a dead short on a few caps near the power switch. With voltage injection and thermal camera, fault is this IC. It's a Texas Instruments chip, but unable so far to properly identify it.

Numbers on it are 2150A TI 761 CQ

As a FYI, this IC has an unusual QFN package layout, known as VQFN-HR-18. Has 5 leads up each side, with 6 at the bottom and 2 at the top.

What threw me on this one is that the number is 215OA, not 2150A. So it's a TPS56215OA buck converter. Here is the link for the datasheet. Now to find where to get one.

Made from unobtainium. Not even TI have this IC in stock. There is another one avail without the OA suffix. Lower current rating (8A vs 10A) but it's a Chromebook so meh. On to the junk pile it goes.
