Microsemi’s LX

LED Driver used to drive LED strings.

The LX23108L has eight internal

current limiters with high bandwidth

PWM controls used to maintain the

required LED current.

The LX23108L is controlled and driven

by the LX

Backlight LED Controller.

Each LX24132 can control up to four

LX23108Ls. The LX23108L can drive

currents of up to 100 mA @ 100%

PWM, or 200 mA @ 50% PWM. The

device is designed to operate with

external sense resistors used for

scaling the LEDs

configuration

flexibility for the system designers to

change

maintaining high accuracy.

A dedicated per channel PWM control

signal coming from the LX24132

enables/disables each of the eight

channels. The LX23108L is available

in a 32 pin, 5 mm x 5 mm QFN

package.
