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
