Description: Automotive LED Driver

Features

* Switch mode controller for boost, SEPIC & buck converters
* Closed loop control of output current
* High PWM dimming ratio
* Internal 40V linear regulator
* Internal 3% voltage reference
* Constant frequency operation with programmable slope compensation
* Linear and PW

Applications

* An internal 40V linear regulator powers the IC eliminating the need for a separate power supply for the IC. The IC provides a FAULT output, which can be used to disconnect the LEDs in case of a fault condition (such as an alternator load dump in automobiles) using an external disconnect FET. AT9917
