Some one knows aboute SMPS schematics with transformer details using TOP-xxx IC or easy one.to make easy design. actually my requirement is primery 220Vac. Secondary 12V -0-12V 1amp and 0 -15V 1amp.


Thanks in advance

Hi,
You can download PI expert tool from power integration site, which is freely available, very interactive and very simple tool for top switch design. Attached is XL sheet solution for your query but still suggest you to download and use it, very useful..
I used 15V, 2A & -12V, 1A O/P. +12V can be derived by using simple LDO. with 3V drop power loss will be max 3W, so definitely under limit.

You can use Table to select the appropriate transformer. After select click to transformers name and get on datasheet with circuits.
