Multi-output backlight LED drivers suit LCD displays

TDK-LAMBDA ALD Series of multi-output dc-dc backlight LED drivers arranged in 2, 3 and 4 string configurations provide wide-range dimming controls with resistive, analog or PWM inputs that provide smooth LED brightness control. Devices provide up to 140mA of constant-current drive to backlighting LEDs that can be connected in series and parallel configurations. Devices operate with an input voltage of from 10.8 to 13.2Vdc and have a maximum open-circuit output voltage of 42 to 44Vdc.
