Linkswitch LNK420

Posted by: Mighty Raskal on 12/06/2016

Hi all,

I m trying to design 50W,1.3A power supply. for that i am using LNK420 (PIXIs designer 9.1.6.3 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.

Here i attach datasheet of LNK420. in that it is mentioned that "this product is not recommended for new designs".

Is there any other solution IC or any new product for my application?
