A dual-channel step-down LED driver, the LT3964 from Linear Technology packs 40 V, 1.6 A power switches and an I 2 C interface for dimming control. Operating over an input voltage range of 4 V to 36 V ...

The LM3463 by Texas Instruments is a six-channel LED driver with dynamic headroom control for high-power applications that accurately drives up to six strings of LEDs. The biggest cost reductions in ...

Solid-state lighting (SSL) differs from conventional lighting in that it uses light-emitting diodes (LEDs) instead of filaments, plasma, or gases. Although still relatively early in its development, ...

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 ...

With LED lighting becoming increasingly popular due to their high luminance, long life, high efficiency and decreasing costs, the subject of controlling and driving the LED's is now a very interesting ...

Control and dimming is an essential feature of many LED-based solid-state lighting (SSL) systems. However, there has been a shortage of standards to ensure compatibility between dimmable LED light ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

Abstract: In this paper, a high dimming ratio LED drive controller without color shift issue was proposed, fabricated and tested. It is composed of a boost power stage and some dimming control ...
