There are lots of suitable chips for SMPS use, the main problem is likely to be the transformer. If you go to rswww.com and search for TDA4605-2 there's a link to a datasheet, which gives an example of a PSU for a TV. For your application the only change would be to the secondary of the transformer.varun said:Hi!
