Other Parts Discussed in Thread: UCC28070A, UCC28070

Is there any use case of UCC28070A Bridgeless PFC?

Customer is concerned about Bridgeless PFC have not example.

Only below application note, but in fact operation example is nothing; customer is thinking.

Best regards,

Satoshi

    Hi Satoshi,
    Yes I agree with you. The information relating to bridgeless pfc is sparse and not complete. It is an issue that TI is looking at and we plan to add more information on this topic. Several customers use bridgeless pfc because of its benefits in increasing efficiency and reducing the effect of crossover distortion.
    However the UCC28070/A is primarily an interleaved controller and so most of the design information is centred around interleaved applications.
    Regards,
    John
