AT9917 Automotive LED Driver

AT9917 Description

Supertex inc.Automotive LED Driver IC with High Current Accuracy .
The AT9917 is an advanced fixed frequency PWM IC designed to control single-switch, boost, SEPIC, and buck LED drivers in a constant current mode.

AT9917 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

AT9917 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
