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 ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

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 ...

A current source is a critical component in most integrated and discrete circuits and can be described as an electric circuit that generates a steady flow of electrons for a given period of time no ...

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 ...

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...

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 ...
