Nearly all lighting applications today use LEDs. In a relatively short amount of time, they have become established as the preferred choice of illumination. However, in most applications, an LED can’t ...

Driving a light-emitting diode (LED) or LED array is not without its challenges. The LEDs require a well-designed constant-current source for controlled brightness. More specifically, the output ...

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 ...

Introduced as the industry’s first LED driver with dynamic headroom control and multiple outputs for high-power applications, the LM3464 promises to maximize system efficiency and reduce system cost ...

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 (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
