Description
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.
Applications
? Low Beam
? High beam
? Daytime running light
? Turn indicator
? Position light
? Side marker
? Fog light
