Have a BMW battery charger which I desperately need to repair.
Have studied the posts discussing how to build such a circuit on this forum. Have also seen the application note on the Pic Micro web site but am still lost.

Here is a picture of the circuit

Anybody willing to take a guess at what the SMD 4 Pin IC which is under the 4 white leds dead center.

Also to its left is a white box marked T2 these are the only two items which are damaged / burnt and need replacing.
Thanks
