The purpose of this project is to control the current across a load by using pulse width modulation for maximum power efficiency while being constructed on a breadboard. The project accommodates the ...

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 ...

A current-limiting circuit is often needed to protect the most expensive parts of the circuit from transients such as current spikes, which occur when a power supply is driving a large capacitive load ...

Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...
