International Rectifier’s IRS29831 LEDrivIR integrates an LED driver controller and a 700-V MOSFET optimized for single-stage flyback and buck-boost topologies used in LED drivers, including LED bulb ...

LED-based light fixtures and bulb replacements arenow rapidly replacing incandescent, halogen, andCFL (compact-fluorescent-lamp) light sources inmany general-lighting applications. Flyback ...

[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] ...

This Idea for Design presents a simple and small solution for driving an LED to provide visual feedback in the presence/absence of a system’s power. Typical requirements for industrial LEDs. Designing ...

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 ...

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Light-emitting diodes (LEDs) have emerged in recent years as ...

To make LED fixtures even more energy efficient, learn how to properly dim the LED lamps. The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting ...

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 ...
