IS31LT3173, IS31LT3172, 10-TO-200MA CONSTANT-CURRENT LED DRIVER
The IS31LT3172 and IS31LT3173 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 2.5V to 42V with a minimal voltage headroom of 1V (t
IS31LT3173 Features
* Low-side current sink - Current preset to 10mA - Adjustable from 10mA to 200mA with external resistor selection
* Wide input voltage range from - 2.5V to 42V (IS31LT3173) - 5V to 42V (IS31LT3172) with a low dropout of typical 1V
* Up to 10kHz PWM input (IS31LT3173 only)
