sg3525+600w smps
we are designing an smps circuit with a/c input of 210-240V 50Hz and an output of 5V and 1A. I went thru the powerint site for devoping smps ckt but it recommends use of linkswitchII(LNK616PG) and EE16 10pin tranformer.
Ref for sch: http://www.powerint.com/sites/default/files/images/schematics/di158.gif
But am interested in building an smps with just a power transistor or a mosfet for switching instead of LNK616PG and a suitable transformer. Can anyone help me out for building such a ckt which is popular in mobile phone chargers???
