LM3463 Constant Current LED Driver

Texas Instruments' six-channel, high-voltage LED driver with Dynamic Headroom Control (DHC)

LM3463 Constant Current LED DriverTexas Instruments' six channel LED driver with dynamic headroom control facilitates development of energy efficient, quality, high lumen-output applications. The LM3463 works easily with readily available, standard constant voltage power supplies, or with customized AC/DC converters which can take advantage of dynamic headroom control for increased system efficiency. Flexible-string dimming control options gives users the ability to optimize the driver for different lighting requirements such as: 1) 6 x white channels (traditional); 2) 4 x white + 1 x red + 1 x green channels (color rendering index adjustment); 3) 2 x red + 2 x green + 2 x blue channels (full RGB).

Features Applications
  • Dynamic Headroom Control output to maximize efficiency
  • Six channel, current-regulated LED driver
  • High precision analog dimming control interface
  • Four individual PWM dimming control inputs
  • Dimming control via digital data bus
  • Street lighting
  • Outdoor area lighting
  • High bay lighting
