[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] ...

Santa Clara, Calif. — National Semiconductor Corp. has designed a Boomer light emitting diode (LED) driver that provides audio synchronization without real-time software processing. The LM4970 LED ...

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 ...

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 ...

This idea describes a white- LED (WLED) driver circuit controlled by a simple ambient light sensor (ALS). A typical application would be a brightness control for cell-phone backlighting. On a very ...

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 ...

LED lights and drivers continue to be among our most rapidly developing technologies with new innovations emerging on an ever-rolling production line (see “LEDs: In The Beginning”). White LED ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...
