    SDH8595AS
    HIGH PRECISION CC/CV PRIMARY SIDE POWER CONTROLLER WITH BUILT-IN MOSFET

        SDH8595AS is offline PSR power controller which operates in PFM to achieve high performance and high efficiency. It integrates a 600V MOSFET and has high-voltage startup function . Both the output current and voltage are sensed by primary side. 

        SDH8595AS removes the need for optocoupler & TL431 while achieving excellent line and load regulation. It also eliminates the need for loop compensation while maintaining stability over all operation conditions. 

        SDH8595AS supports applications up to 15W.
