Abstract: Static constant-current circuits have been constructed by connecting an iron-core reactor, with predetermined characteristics, in parallel with a capacitor of a specified size such that the ...

This application note shows how to use linear voltage regulators to provide a constant current. Two circuits are presented, one for high-side and another for low-side current sources. The MAX1818 and ...

Abstract: A network theoretic approach is employed to derive a number of circuits for i) constant load current, ii) constant load voltage, and iii) constant magnitude input current, when the load ...

You need to know how to investigate how current changes with voltage for a component, eg for a resistor (or wire) at constant temperature, a filament lamp and a diode. You should be familiar with the ...

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...

This project is part of LibroDuct. We decided to publish some results of our LED driver designs to support the opensource maker scene. Feel free to use those results in your designs. All those designs ...

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 ...

Described as the industry's first ac/dc-isolated LED driver modules with constant-current circuits optimized for driving high-intensity LEDs, the BP58xx series integrates all necessary LED-driving ...
