    Dear Tony,

    Thank you for contacting TI.

    I would like to highlight a reference design we have done for interleaved CCM. Although this design in not with the UCC28070, it provides a very example and detailed explanations for this topology. Please take a look and let us know if you have questions.

    Thanks.

    I understand that TI's advice is to use GAN at Interleaved CCM Totem Pole Bridgeless. Currently we use UCC28070 and Cool MOSFET if we use GAN MOSFET directly and increase the frequency. Is it possible to increase power in the current volume? Do you have a suggested reference?

    Hello Tony,

    UCC28070 is not a totem pole controller and is not the right controller for this application. I recommend considering one of the reference designs that we have for totem pole such as the one I linked on the previous response.

    Thank you.
