    • Integrated 650V MOSFET
    • Charge Pump PFC LLC Topology with Low BOM Cost
    •  PF>0.95, THD<20%
    • Primary Side ILED Regulation and Less than 2% ILED Ripple
    • Short LED Protection (SLP), Open LED Protection (OLP), E-cap over Voltage Protection (HV OVP)
    • Zero Voltage Overshoot on Resonant Capacitor at Startup
    • Compact Package: SO8

    The SY59526 is the high 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 BOM cost a lot. Meanwhile, the LLC topology improves efficiency and EMI.

    The SY59526 should work with SY59525, which is the low side LLC controller integrated with a 650V MOSFET.
