IS32LT3128 TRIPLE CHANNEL LINEAR LED DRIVER

IS32LT3128 TRIPLE CHANNEL LINEAR LED DRIVER

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; no microcontroller is required. Extern.

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
• Selectable external or internal PWM source - External PWM directly drives the current source - Internal 220Hz PWM source with Gamm.
