    Hello Yang, I the datasheet for UCC28019A limits its application for less than 2kW and honestly for such high power levels I would recommend using an interleaved CCM controller like UCC28070A. Please find attached a reference design for a 3kW power supply…

    Hi Dante, Thanks for your interest in UCC28070. Starting on page 29 of the UCC28070 datasheet is a design example which can help you to select the passive components for the PFC stage. You also might have interest in PMP4259 which is a 3kW PFC stage…

    Hi I assume you need an 85Vac to 265Vac input voltage range? The output is 1.2kW so it will most likely need a PFC front end to converter the AC line to a 380V to 400V BUS and then a phase shifted full bridge to converter the PFC DC voltage down to 12V…

    Did you build the PMP4259 reference design ? Or are we still talking about the pfc circuit attached in the initial question? Have you found out what is pulling the SS pin low? The PMP4259 reference design does not have Q5 in the BOM and it is not fitted…
