Integrated Circuit ID

2 posts / 0 new

Can you please tell me which Power Integrations integrated circuit is this burned one? I still can see the last numbers, "37" I think.

It's from a NOX NX Series 520W computer power supply.

NOX can't help me but I need to buy and replace it with the right one.

The "37" refers to the last 2 digits of a lot number not to PN. Generally, PI PN ends with letter. It is very difficult to identify the IC by only the last 2 digits of a lot. It can be any PI IC.

Hope this helps,

Thanks and Regards,

PI-Lupin the Third
