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. To achieve better light load performance, HV start up design is added .In addition, SY23404 has cable compensation to regulate the output voltage for better load regulation at cable terminal.
