This is a simple 230 V LED Driver circuit which is accomplished using a capacitor based power supply. This is a low cost and efficient circuit and can be used at homes. Here we design a simple circuit ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...

There are many applications for LED lighting, from simple incandescent or CCFL lamp replacement to new opportunities in architectural, industrial, medical, and other applications. Each of these ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

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 ...

Supertex, Inc. has introduced the HV9910, which it describes as the industry's first universal, high brightness (HB) LED driver IC. The HV9910 is a highly flexible and simple LED driver IC that ...
