IS32LT3128A - TRIPLE CHANNEL LINEAR LED DRIVER

Datasheet Summary

Description

The IS32LT3128A 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.

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 - Lower priority than PWM input - Gamma corrected Fade ON/OFF algorithm - Pull down resistors set independent fade ON and OFF ramp time.

IS32LT3128A TRIPLE CHANNEL LINEAR LED DRIVER WITH FADE ON/OFF AND PWM DIMMING GENERAL DESCRIPTION The IS32LT3128A 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. External resistors will program the current levels as well as the LED fade ON/OFF ramp rate. Additional configuration such as PWM source (internal or external), polarity (positive or negative) and switch type (momentary contact or latched) are selectable via the MODE1/2 pins.
