A cascode configuration reduces reference modulation error in a 4-20 mA current mirror, improving active impedance by orders of magnitude.
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 ...
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 ...
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 ...
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 ...
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 ...
