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).
