LM3463 Constant Current LED Driver



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


Texas Instruments LM3463 Constant Current LED Driver Texas 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).
