UCC28070: Feedback by photocoupler

Kuramochi Tadahiko

Part Number: UCC28070

Hi,

My customer is requesting to feedback the signal by not transformer but photocoupler on the UCC28070 PFC circuit.

Do you have any reference design?

Best Regards,
Kuramochi

    Hello Kuramochi,

    The UCC28070 is a pfc controller for use in a non-isolated boost type converter.

    There is no reference design available that uses an opto coupled  feedback.

    What is your customers application and why do they require opto coupled feedback ?

    Regards

    John
