Description:

10-to-150ma constant-current led driver.

IS31LT3170, 10-TO-150MA CONSTANT-CURRENT LED DRIVER

The IS31LT3170 and IS31LT3171 are adjustable linear current devices with excellent temperature stability.

A single resistor is all that is required to set the operating current from 10mA to 150mA.

The devices can operate from an input voltage from 2.5V to 42V with a minimal voltage headroom of 1V (t

IS31LT3170 Features

* Low-side current sink - Current preset to 10mA - Adjustable from 10mA to 150mA with external resistor selection

* Wide input voltage range from - 2.5V to 42V (IS31LT3171) - 5V to 42V (IS31LT3170) with a low dropout of typical 1V

* Up to 10kHz PWM input (IS31LT3171 only)
