IS32LT3124B - LINEAR LED DRIVER

Download the IS32LT3124B datasheet PDF. This datasheet also covers the IS32LT3124A variant, as both devices belong to the same linear led driver family and are provided as variant models within a single manufacturer datasheet.

General 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.).

Key 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.
