UCC28704: can it support DC input voltage up to 450V?

Part Number: UCC28704

Customer is looking for a PSR flyback controller for their aux power.  The input is from their PFC output, so the input voltage range might from 300V to 450V. Could you please help check whether UCC28704 or other better proposal can support their requirement?

  • Hi Aki,

    Yes. Any of our flyback controllers can support this. The key is making sure the external components are properly rated. As for making a better recommendation, what is the power level for the load?

    I hope this answers your question.
