    What three conditions does the UCC28610 need to start the next cycle modulator?


    *
    Answer

    (1) Since the time of the last open edge must be equal to or greater than the time required for the feedback process, it is determined by the feedback current repulsion 8.

    (2) Since the last open edge must be longer than the minimum period established by the UCC28610 (usually 7.59s at 133kHz).
