SF5922 switch equivalent, high precision primary side regulation (psr) cv/cc power switch.
* Built-in 600V Power MOSFET
* Low Standby Power Under 30mW, Easily to Pass Energy Star EPS2.0
* Primary Side Regulation (PSR) without TL431 and Opto-Coupler .
SF5922 uses Pulse Frequency Modulation (PFM) control to improve efficiency and eases system EMI design. The IC dramatic.
