    Hello Red,

    The following Simplis model for the UCC28064 (  ) is available for download from the TI product folder http://www.ti.com/product/UCC28064A/toolssoftware .

    I ran a transient simulation straight from the down-loaded file and it took ~15 minutes to simulate 400ms of PFC operation.
    The load is a 1K resistor, but the user can modify the schematic to include step-load changes, etc.

    Be sure to read the notes listed beneath the schematic diagram for limitations of the model.

    Regards,
    Ulrich
