RoHS: Compliant
View Datasheet Manufacturer Site View Pricing & Stock

The L99LD20 is a flexible LED driver, which is specifically designed for the control of two independent high brightness LED strings for automotive front lighting applications. It consists of a high efficiency monolithic dual buck converter. The buck converters integrate n-channel MOSFET which is driven by a bootstrap circuit. When more than two LED channels are required on one module, then more devices L99LD20 can be combined; also with L99LD21 device - incorporating Boost Controller - from which L99LD20 derivate.
