This project is made out of few junkbox parts and builds a useful constant current load for switch mode power supply, battery testing, and other applications. A dummy load is traditionally a big ...

When applying white LEDs for display backlighting or other illumination applications, there are two reasons to drive them with constant current: (1) To avoid violating the Absolute Maximum Current ...

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 ...

Most of us are used to thinking in terms of voltage sources so there is rarely a day goes by that we do not think about voltage source loading or use Thevenin’s theorem. But what about current sources ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

ON Semiconductor has expanded its portfolio of Constant Current Regulators (CCRs) to include the NSI50350A. ON Semiconductor has expanded its portfolio of Constant Current Regulators (CCRs) to include ...
