Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...

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 ...

Supertex has introduced an LED lighting chip with switch dimming. The IC, dubbed HV9801A, dims LED lamp brightness to one of four preset levels through rapid toggling of a light switch. Light levels ...
