A very special circuit was designed to drive the LEDs with a constant current to be used for variety of LED applications. A very special circuit was designed to drive the LEDs with a constant current ...

Operating a stepper motor using a fixed (constant) voltage supply results in poor torque at high speeds. Operating a stepper motor using a fixed (constant) voltage supply results in poor torque at ...

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 ...

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

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 ...

This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with many integrated analog features. The LED driver ...

Many embedded systems require a stable, low-noise DC reference. This reference can be a stable current or voltage source. These references are used in many ways. Some typical uses are listed as ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...

Current source inverters and converters represent a crucial class of power electronics devices that convert direct current from a constant current source into alternating currents with precise control ...
