If you are looking to replace halogen bulbs with LEDs, combining a rectifier bridge and a current-controlled synchronous step-up/step-down converter creates a high power factor driver circuit, writes ...

The advent of high-power LEDs that can replace incandescent bulbs has produced a need for circuits that efficiently match the LEDs to available power sources (batteries, car electrical systems, etc.).

CCFL backlights are the most common backlight technology and are used in displays ranging from 5.7 to 23 in. or more diagonal. They can have from one to 24 or more lamps mounted along the edge of the ...
