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.)
