Hi Brian,

For my own understanding, is this single phase 311Vac to 515Vac? What is the line frequency for this design spec?

Best Regards,
Ben Lough

Yes, this is single phase Vac input, and the line frequency is 50-60Hz. Pls advice what reference design and device is suggested. Thanks!

Hi Brian,

Thanks for the additional information. At 200W, transition mode PFC would be a good choice. We don't have any reference designs (TM or otherwise) for this input voltage range unfortunately. I recommend taking a look at UCC28051.
