I can't seem to find a datasheet either. But looking at images on eBay, it looks either to be a regulator of some sort or a MOSFET... or less possibly, a controller for a VRM.

Are there thick traces connected to any of the pins on this chip? Any of them low resistance reading (under 100 Ohms) to ground? If yes, it's probably a regulator or MOSFET.

Somewhat good news is that at least they are available to buy on eBay. So bad comes to worse, maybe replace it if in doubt.

Also would be good to know more about your motherboard troubleshooting: i.e. what is the board doing and how did you conclude that this component is shorted? Does it look burned or with a hole in it? Heat-discolored? The more we know, the more likely someone may be able to point you to a solution.
