SY22748 is the low side LLC controller integrated with a 500V MOSFET, it is used in charge pump PFC application. High PF is achieved by inherent PFC function and low LED current ripple is achieved by LLC topology. Single stage structure and primary side regulation save BOM cost a lot. Meanwhile, LLC topology improves efficiency and EMI.
It should work with SY22749, which is the high side LLC controller integrated with a 500V MOSFET
