[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] ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Diodes has released simple LED driving chips for regulating current in strings of LEDs, particularly in cars and other road vehicles – some of which match parts from Infineon and Nexperia (see table ...

A white LED delivers a wide color spectrum and better visibility than do monochromatic LEDs. However, a white LED presents a higher forward-voltage drop than do its colorful counterparts and thus ...

With only a few additional components,you can use a highlyefficient step-down dc/dc converter tocreate a constant-current, multiple-channelLED driver. It is relatively easyto drive a single-channel ...

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 ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

Light-emitting diodes have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...
