(2 pages)
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.
