    EVB_SY23406Z

    SY23406Z is a single stage Flyback regulator targeting at Constant Current/Constant Voltage (CC/CV) applications. It integrates a 600V/2Ω MOSFET in a compact SO8 package to minimize the size. Both the output current and voltage are sensed on the primary side, eliminating the opto-isolator and the secondary side feedback circuitry, and minimizing the overall system cost.
