'[OT] Switching Power Supply'

I have a small wall mount switching power supply and it
uses a TO-220 IC, It takes the 120V and regulate ~5V
via a small transformer.
Any clue about what IC could it be?

Friendly Regards

My guess would be either one of the TOPSwitch or TinySwitch parts from Power
Integrations (http://www.powerint.com)  - they're basically three-pin
offline switchers.
Either that or Motorola makes some compatible parts, though I can't think
of the
part numbers offhand (MC3337X, I think, but I'm not sure on that.)
