Typical Application Circuit
General Description
WS3231 is a high PF primary-side feedback and
regulation controller for LED lighting, optimized for flyback
converter with the output power less than 30W.
Since adopting primary sense and feedback control
technology, the secondary sense and feedback circuit is
eliminated. And WS3231 does not need the auxiliary
winding for sensing the output current and supplying the
chip. The low component counts and small system size
are realized.
Since using the high accurate current sense method,
WS3231 realizes ±5% accuracy of LED current along with
excellent line and load regulation.
WS3231 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.
WS3231 is available in SOP-8 package.
