High Power Three-Channel LED Driver

Keith Szolusha - Applications Engineering Section Leader Oct 27th 2014
Large arrays of LEDs require high power and multi-string LED drivers. When many single channel, high power converters are used in an application, a better solution may be to reduce the cost and number of components by using a single converter with several drivers on the same IC. Eliminating or reducing duplication of features ...
