WINSEMI WS3230
WS3230 is a high precision QR primary-side feedback and regulation controller for LED lighting, optimized for flyback converter with the output power less than 30W. The low component counts and small system size are realized. WS3230 offers comprehensive protection including Cycle-by-Cycle current limiting (OCP), LED open/short circuit protection, CS resistor short circuit protection, VCC UVLO,OVP and Clamp, and over temperature protection.

FEATURES
±5% LED Current Accuracy Primary-side Sensing and Regulation Without TL431 and Opto-coupler No Auxiliary Winding For Sensing And Supplying High Power Factor Correction Ultra low operating current LED Open/Short Circuit Protection CS Resistor Short Circuit Protection VCC over voltage protection & under voltage lockout( UVLO) Over Temperature Protection APPLICATIONS
GU10 LED driver LED spot light Other LED lighting GENERAL DESCRIPTION
Since adopting primary sense and feedback control technology, the secondary sense and feedback circuit is eliminated. And WS3230 does not need the auxiliary winding for sensing the output current and supplying the chip. Since using the high accurate current sense method, WS3230 realizes ±5% accuracy of LED current along with excellent line and load regulation. WS3230 is available in SOT23-5 package.
