Ic identification

Posted by: goshuoz on

 

 

Hi All

 

Kindly inquire to identify the Power Integration IC that is blown out from High power SMPS.

Only three last letters left from the IC and I'm not sure it is a part number or some manufacturer code.

"....903" is the only visible left from the IC

I attached here a photo for your further information.

 

thank you in advance

The IC you are talking about is known with the IC 903. It is the ESD suppressor IC. You can find it from many companies. But you must choose the one which suits to the configuration of your SMPS.
