Burnt IC on power board ATU-100


Kj7OCO
 

Well, it looks like the 8 pin IC took the easy way out.......burnt up!

I just bought the device and plugged it into a 12DC supply using the front mini-usb port.

I have been pouring over the schematics and see U2 i believe. Not sure if that is the right component.

So the big question is.....can i buy new power board (assuming that is what it is) or am i going to have a buy a new unit?

Any help greatly appreciated.
