Even if you are designing a microcontroller-based LED display system, often it may calls for a manual option to control brightness of the LED display unit. On the otherhand, if it is based on discrete ...

We know that LED is a two terminal semiconductor device. It is used in most of the electronic circuits as a sign or visual representation to the normal human to know that circuit is working properly.

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

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 ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

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 ...

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 ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...
