Three phase SMPS 3.2Watts

3 posts / 0 new

I want to make three phase smps with below specification


Input voltage - 150V to 500VAC

DC output Voltage 1: 4V @ 500mA (main voltage i.e. regulated voltage)

DC output Voltage2: 12V @ 100mA


Can anybody give me schematic & transformer specification for the same?

Note: If possible I want this SMPS design based on TNY268.




TNY268 can not works with 500Vac.

yes you can do that ..
