WEBENCH® Tools/UCD3138064A: Design UCD3138 as AC-DC 1000W

Part Number: UCD3138064A
Other Parts Discussed in Thread: UCD3138

Tool/software: WEBENCH® Design Tools

Hi Gents, I only get info that UCD3138 can design as 2 phase interleave PFC or LLC DC-DC converter, but I want to select one UCD3138 design combine PFC circuit like AC to DC 12V/1000W.

  • Hello, Sean,

    If you want to use one chip for two power stages, UCD3138 is doable. But there is a lot of isolation barriers such as voltage feedback and monitoring, and current measurement, and so on. A common solution is to use two small packages of UCD to control primary side and secondary side.

    Regards,
    Sean
