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 ...
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 ...
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 ...
Performance specs can be trumped, but elegance persists. Consider the most basic task in industrial control: driving sensors and bridges. It doesn’t matter if you’re dealing with a strain-gauge bridge ...
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 ...

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 ...
A blisteringly fast 400V monolithic gallium nitride power buck converter featured at the International Solid-State Circuit Conference (ISSCC) this week. Its figures speak for themselves: 50MHz ...
