IS32LT3128 Overview
The IS32LT3128 is a programmable triple channel linear current regulator; two channels of up to 150mA each for LED lighting and a single channel of up to 30mA for illuminating switches. The device operates as a fully configurable theatrical dimming LED driver;.
IS32LT3128 Key Features
- Operating voltage range, 5V to 42V
- Dual channel current sources
- Individual programmable current via a single external resistor
- Configurable from 20mA to 150mA
- Single channel 30mA (Max.) current source for switch illumination
- EN input supports either momentary contact or latched switch
- Input is debounced and latched
- Higher priority than PWM input
- Gamma corrected Fade ON/OFF algorithm
- Pull down resistors set independent fade ON and OFF ramp time
