SD8530AS is primary side regulator (PSR) with built-in high voltage transistor. It provides built-in cable drop compensation and peak current compensation. It adopts PFM technology and provides accurate constant voltage, constant current (CV/CC) control loop for high average efficiency and reliability.

    Using SD8530AS for system design, few peripheral components are needed without requiring the Opto-coupler, Y capacitor, secondary control circuit and the loop compensation circuit which reduced the cost.

    6W output power is recommended for SD8530AS in range of AC85~264V.
