Subject: Need help with Offline Switching Supply from uProcessor


Has anyone tried using the processor to control an offline switching
power supply?  What I would like to do is use the processor to regulate
it's own power supply directly off the AC line. I don't need a lot of
current, but I need 12 volts to drive a dc relay.  Any suggestions?
