  • Hi Shotaro-San,

    Thank you for reaching out.

    UCC28780 and UCC28782 follow the same control law but the only difference being - UCC28782 comes with emi  dithering and has boost controller pins for supporting wide output voltage operations.

    Yes UC28780 can be put on the board but there is considerable difference in size of package between the two. So soldering this might be a challenge.

    Regards,

    Harish
