Description: High Precision Primary Side Regulation (PSR) CV/CC Power Switch

Features

* 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
* ± 5% Constant Current (CC) and Constant Voltage (CV) Regulation at Universal AC Input
* Proprietary Cable Voltage Drop C

Applications

* SF5922 uses Pulse Frequency Modulation (PFM) control to improve efficiency and eases system EMI design. The IC dramatically lowers system cost by eliminating the opto-coupler and secondary control circuits. It also can provide very tight output voltage regulation (CV), in addition to output current
