This is the first basic LED circuit I built many years ago in my school days and had given me immense pleasure to see glowing LED. For building this circuit you only need four things: LED- 1; Resistor ...

The above circuit is designed to drive a LED with 0.2A. This current rating is fixed by the Resistor R1 in the circuit. The formulae to determine the current is. I = Vref/R1 where, Vref is 1.25V for ...

In the diagram as you can see two LED’s are placed in opposite directions so when one LED is ON the other LED will be OFF. I have used Red and Green LED’s. When node A is positive green LED glows ...

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.

Renesas Electronics announced the availability of the R2A20134EVB design support tool for the R2A20134. It comes mounted with the R2A20134, a high-efficiency LED driver IC for applications such as LED ...

In this paper, a fast-switching current-pulse driver for dimming controllers of light-emitting diode (LED) backlight applications is proposed. A pair of current switches, which is used for driving the ...
