The L99LD21 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 boost controller and a dual buck converter.
The boost controller integrates a high current gate driver for an external n-channel mosfet. It delivers a constant output voltage, up to 60 V, which supplies the inputs of the two integrated or external buck converters.
The boost controller of two devices can be stacked, in order to operate in dual phase for high power applications, with an interleaving pattern for an improved input current ripple.
The buck converters integrate n-channel mosfet which is driven by a bootstrap circuit.
