High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

Typical requirements for industrial LEDs. Designing an LED gate driver using an industrial digital input chip. Ruggedness characteristics of the new gate driver. Industrial control systems universally ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...

This white-LED driver circuit is ideal for use in a garden light. It automatically turns the LED on at night and runs from a single 1.2V nicad cell which is recharged by a solar cell during the day.

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 ...
