This app note provides a simple circuit to drive high brightness LEDs. It requires minimum external components and it provides both linear and PWM dimming. Ideal for Osram, Lumileds, Cree, and Nichia ...

This is a simple 230 V LED Driver circuit which is accomplished using a capacitor based power supply. This is a low cost and efficient circuit and can be used at homes. Here we design a simple circuit ...

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 ...

1. A Cree XM-L RGBW high-power LED can be driven by two LT3964 LED drivers for accurate 1:8192 per channel dimming. 2. Typical driver architectures offer 8-bit color resolution. Implementing a driver ...

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 ...

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 ...

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 ...

Schaffner has added the ED100/ED101 EMC filter series for LED driver circuits. The new filter’s common-mode inductance is matched by a substantial differential-mode inductance. With only one component ...

With the new driverless AC technology of euroLighting, completely new opportunities open up for the development of LED lighting. The complete circuit with 40W including LEDs fits on a compact 80 x ...
