[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 ...

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 ...

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 ...

Tagging wildlife is never straightforward in the best of times, but it becomes a great deal more complicated when you’re trying to track flying insects. Instead of trying to use a sensor package, ...

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 ...

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 ...

In this article, we continue our discussion on the importance of grounding when installing LED lighting equipment. Part 1 of this three-part series focuses on the ground plane of the printed circuit ...

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 ...

In Part 1 of this three-part series, we discussed the importance of a well-engineered PCB ground plane for LED drivers, so the ground plane can be effective in managing disturbance energy generated ...
