IS32LT3177 Datasheet - Lumissil

IS32LT3177 10-TO-200MA CONSTANT-CURRENT LED DRIVER

The IS32LT3177 and IS32LT3178 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 .

IS32LT3177 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 (IS32LT3178) - 5V to 40V (IS32LT3177) with a low dropout of typical 1.0V at 150mA

* Up to 1kHz PWM input (IS32LT317
