Hi.
Two SOIC ICs in a switched power supply, 100-240 VAC -> 18.5 VDC

1: 8 pin, seems to have a ST logotype, marked "M103AI" and "K131"

2: 16 pin, ST logotype, marked "LITEON99" and "90E127".

One (or both ?) "should" be a switched power supply controler...

Any info on these are welcome !

Jan-Erik.
