    EVB_SY23404

    SY23404 is a single stage Flyback controller targeting at Constant Current/Constant Voltage (CC/CV) applications. It integrates a 700V MOSFET to decrease physical volume. Both the output current and voltage are sensed by primary side signal process. SY23404 operates quasi-resonant mode and adaptive PWM/PFM control for highest average efficiency.
