Hi all,

I m trying to design 50W,1.3A power supply. for that i am using LNK420 (PIXIs designer currently i m using).

In my design output line regulation is not proper. if i adjust line regulation and try to set output current, again line regulation get affected. there is no proper datasheet for LNK420. Vpin resister values how to set, in tool it is not showing. Here i have attached pixis designer.

Expecting a helpful reply.
