    While UCC28064A+UCC25630x can get below 300mW for standby power as TIDA-010015 shows, it cannot cannot meet such a stringent standby power requirement of under 100mW when PFC and LLC stage are both on.

    If the PFC is disabled, and the aux power comes from an aux flyback converter from a low standby device like UCC28730 or operates off an LLC controller that can support a wide input voltage like UCC256304, it should be able to meet this requirement.

    Best Regards,
