WS3231 - High PF PSR Constant Current LED Driver

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.

Key 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.
  • QR mode.
  • 600V MOS integrated.
  • 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.
