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 ...

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 ...

[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] ...

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 ...

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 ...

Sponsored by Texas Instruments: The LED is the dominant lighting solution today, but the processes involved in driving and dimming them are more sophisticated than you perhaps thought. Light-emitting ...

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 ...
