Hi

Can anyone tell me wich chip should I use for isolated 220v to 12v switching power supply. (20-40w autput power)
 

Re: 220V to 12V switcher

See the following doc for your requirement. You can also use LM3524 or SG3525 etc. And by the way it is not the IC, it is the way it is used to isolate.
 

220V to 12V switcher

For 20-40W flyback is good choice, TOP221-227 from PowerIntegration is a simple suggestion.
