Datasheet
SY22861CFAC Flyback controller for adapters or chargers Datasheet
    • Quasi-Resonant (QR) mode operation: Valley turn-on of the primary MOSFET to achieve low switching losses 
    • Output current is monitored by primary detection for reliable Over Current Protection and Short Circuit Protection
    • PWM/PFM control for higher average efficiency
    • Burst mode control for improved efficiency
    • Low start up current: 4μA Max
    • Maximum frequency limitation 125kHz
    • Auto-Recovery OVP/OCP/SCP/OTP
    • Integrated 600V MOSFET
    • Compact package: SO8
