SDH8592AS
HIGH PRECISION CC/CV PRIMARY SIDE POWER SWITCH WITH INTEGRATED MOSFET

SDH8592AS is a high performance off-line PSR power switch which operates in PFM to achieve high performance and high efficiency. It integrates a 650V MOSFET and high voltage startup to decrease physical volume. Both the output current and voltage are sensed by primary side signal process. 

SDH8592AS removes the need for secondary feedback circuitry while achieving excellent line and load regulation. It also eliminates the need for loop compensation while maintaining stability over all operation conditions.
