General Description

The IS32LT3143 device is a linear programmable LED driver consisting of three current source output channels capable of up to 150mA each.

It supports individual PWM dimming control to each channel.

A single resistor sets the maximum current level for all channels.

Overview

IS32LT3143 THREE-CHANNEL LINEAR LED DRIVER WITH INDIVIDUAL PWM DIMMING AND SINGLE LED SHORT DETECTION May 2024.

Key Features

  • Wide input voltage range: 5V~40V.
  • Three output channels with programmable constant current set by a single resistor ̵ 10mA to 150mA per channel ̵ ±2% (Typ. ) current matching by channel (IOUTx >30mA) ̵ ±3% (Typ. ) current accuracy by device (IOUTx >30mA) ̵ Combined multiple channels or ICs for higher current capability with same current accuracy.
  • Low headroom voltage ̵ Max. headroom: 500mV at 60mA per channel ̵ Max. headroom: 1.1V at 150mA per channel.
  • Independ.
