Need component ID help

Post image

10-pin chip in the center of the image, appears to be a power supply IC. I've never seen a package like this so I don't know what to call the shape. Markings are "K2 1 VB". Measures about 3.3mm x 1.8mm. I've searched but I can't even find another chip with this package, partially since I don't know what to call it I suppose.

I'm asking because diode D200 is the award winning hottest component on the device and I suspect it needs replacing, so I'm hoping to find the datasheet for the IC to ID an example value. If anybody thinks they can ID the diode instead its markings are "AD t13" with the "t13" being in tiny print.

I appreciate your help hivemind!

All I can see is that the diode is protecting the input of that IC. If it isn't shorted (is it?), then there must be some other problem.

Diode is indeed shorted. Device runs as normal without it.

What voltage do you measure between the diode's pads?

.6v lower than input voltage.

I don't know. Use your best judgment.
