How do we implement loop compensation in UCC28730 as well as other such Light load efficient flyback controller?

There's no COMP pin available.

    Hi,

    Thank you for reaching out on the UCC28730 query.

    The UCC28730 is internally compensated PSR controller and there is no need for external compensation. You can check UCC28740/50 for external compensation with optocoupler.

    Please follow the excel calculator for design.

    Regards,
