Hi,

Could you please advise us the solution to increase output power through Multi-Parallel connection by "Single PFC / Transition Mode with Zero Current Turn-on" device?   If TI has any reference design, please let us know.

Thanks and best regards,
M.HATTORI.

    Hi Mattori,

    unfortunately there is not a reference design that use single CRM controller to achieve multi-phase PFC.

    There are UCC28065 in TI for two phases interleaved and I remember Onsemic has three phases interleaved PFC controller, you should be able to search from On's website.
