IS32LT3124E - LINEAR LED DRIVER

This page provides the datasheet information for the IS32LT3124E, a member of the IS32LT3124A LINEAR LED DRIVER family.

Datasheet Summary

Description

The IS32LT3124 is a linear programmable current regulator consisting of 4 output channels capable of up to 150mA each.

Individual external resistors set the maximum current level for each channel.

The outputs can be combined to provide a higher current drive capability up to 600mA (Max.).

Features

  • Dynamic Headroom Control (DHC) with an optional external PMOS FET to minimize IC thermal stress when the supply voltage exceeds the LED string forward voltage. It includes two modes for different output power: Shunt Regulator mode and Series Regulator mode. It can operate with power supply modulation (PSM) for.
