WS2811AF is a 12 V three-channel RGB constant-current LED driver for individually controlled LED strings and strips using a 24-bit single-wire cascade protocol.

Best for

  • 12 V RGB LED pixel strings
  • Cascaded RGB LED strips
  • COB and point-light LED products

Avoid if

  • Applications requiring documented RoHS, REACH, or lifecycle status
  • Designs that require a supply voltage outside 10.5 V to 13.5 V

Check before use

  • DIN high-level compatibility: 3.0 V minimum
  • 24-bit RGB byte ordering: R, then G, then B
  • Reset low time of at least 200 µs
  • Actual supported serial data rate
