The basic LED driver is powered by 5 to 48 Vdc and uses a dc/dc boost converter to provide voltage to a constant-current driver that drives the LED string. For quality performance, a constant-current ...

Color LCD displays require a white backlight for proper viewing in any lighting environment. This backlight subsystem consists of an array of high brightness white LEDs, a diffuser to distribute the ...

Closed-loop CCFL drivers provide constant strike voltage and current over a range of input voltages. As a result, they’re more desirable in applications that don’t have a regulated input.

LED applications are booming: backlighting for LCD TVs, projectors, and computer displays, camera flashes, and vehicle brake lights and taillights are just a few. All require constant-current LED ...
