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 ...

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 ...

Figure 1’s negative constant current source has been a textbook application for the LM337 regulator forever (or thereabouts). It precisely maintains a constant output current (Iout) by forcing the ...

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 ...
