Part Number: UCC3804

Tool/software: WEBENCH® Design Tools

HI Support,

      I am developing a Power board  with   INPUT VOLTAGE:- 20-1000V      OUTPUT VOLTAGE:-  12V @2amp

      it is an isolated flyback converter.

      I have gone through Webench design and selected the design based on the UCC3804D controller.

   

    After designing Board

    There was no 12 Volt output.    Some time changing RT register value, I can find around 5.6v output. but in this case POWER MOSFET heated up.

  • Hi Deepak,

    I found that it used UCC2813DTR-4 device in the attached WEBENCH module, rather than UCC3804D, could you please check it. Thank you.

    Regards,
    Teng
