DCP022415D: DVB dual output package

Part Number: DCP022415D

I am using a DVB package dual output version. I have a burn mark next to pin 26 on the top of the chip which is an NC connection.  I am just wondering what would be in that area on the chip that may overheat so I can try to root cause this.  Thank you.

  • Chris:

    DCP022415  primary side area , Pin 1( +Vs), pin 2 (-Vs) and pin 28 ( Sync)  with NC pins 26,27 has the power controller located in this area. Based upon your case burn mark comment, it appears the power IC has been overstressed.

    What is the application for this converter? Is it a IGBT power FET power drive on the secondary ?
