SDH8594ES
HIGH PRECISION CC/CV PRIMARY SIDE POWER SWITCH WITH INTEGRATED MOSFET

    SDH8594ES is offline PSR power controller which operates in PFM to achieve high performance and high efficiency. It integrates a 650V MOSFET and has high-voltage startup function . Both the output current and voltage are sensed by primary side. 

    SDH8594ES 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. 

    SDH8594ES supports applications up to 12W.
