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.

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 ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

LEDs are more efficient than incandescent lights and can last 100 times longer, but they require specialized electronic-drive circuits to avoid overstress conditions. The main operating parameter 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 ...
