    Hello Robin,

    The UCC28780 is an off-line flyback controller implementing the complimentary active-clamp topology variant. We have no other controller in the flyback category as sophisticated as this device, but there is a broad UCC287xx family, along with UCC286xx, UCC2888x, UCC289xx and LM5021 & LM5023 families of more general purpose and specific purpose flyback controllers.
    All of these controllers are available in SOIC-8 and/or SOT-23-6 packages.
    In addition, another part of our product line carries a number of active-clamp forward-mode controllers, mostly in DC/DC conversion.

    The smallest package available of any of the flyback parts is the 3x3mm QFN option for the UCC28780 only (UCC28780RTE).
    It also comes in a larger SOIC-16 version (UCC28780D).

    But essentially, at this time there is nothing else like the UCC28780 and nothing is smaller.

    Regards,
    Ulrich

    Ulrich: wow: thanks for putting all of a category in one line! Yeah, I noticed the QFN pkg & going to have use that. Plan is to pack it all up with 16 mm sq by 12 mm! say 5V @4 amp. That is mighty small but we have excellent thermal control. Input 380V
