The SY59525 is the low side LLC controller integrated with a 650V MOSFET, it is used in charge pump PFC application. The high PF is achieved by inherent PFC function and the low LED current ripple is achieved by LLC topology. The single stage structure and primary side regulation save the BOM cost a lot. Meanwhile, the LLC topology improves the efficiency and EMI.
The SY59525 should work with SY59526, which is the high side LLC controller integrated with a 650V MOSFET.
