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 ...

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 ...

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 ...

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 ...

Using pulse current charging, or a constant current divided with a few short breaks, lithium-ion batteries hold up better over hundreds of charging cycles and can last twice as long. When you purchase ...

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. This simple and extremely robust device is designed to provide a thermally efficient and ...
