IS31LT3177 Datasheet (Lumissil) - 10-TO-200MA CONSTANT-CURRENT LED DRIVER

IS31LT3177, 10-TO-200MA CONSTANT-CURRENT LED DRIVER

The IS31LT3177 and IS31LT3178 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 200mA.

The devices can operate from an input voltage from 2.9V to 40V with a minimal voltage headroom of 1.0V

IS31LT3177 Features

* Low-side current sink - Adjustable from 10mA to 150mA (SOT236)/200mA (SOP-8-EP) with external resistor selection

* Wide input voltage range from - 2.9V to 40V (IS31LT3178) - 5V to 40V (IS31LT3177) with a low dropout of typical 1.0V at 150mA

* Up to 1kHz PWM input (IS31LT317
