    Hi Gabriel,

    Thank you for the query on UCC28070.

    To be honest, UCC28070 has not been tried and tested in the DC buck configuration. One of the concerns is if the current synthesizer can still work ok if using the device in buck PFC. The down-slope of current is calculated/estimated inside of the IC with the intended use with boost concerter.

    You can check with UCC28220 for this application.

    Regards,

    Harish
