This PWM Controller circuit is ideal for controlling small motors with 2A maximum current consumption. For higher currents you need additional cooling for T2 and increase C2 value. This pwm motor ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...

This article is part of the 2022 April 1st series in the Humor topic within our Series Library. The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 ...

A cooling system can sometimes be a buzzkill. You drop your badass engine into your badass hot rod, and then you remember you've got to keep it cool. As an afterthought, you order a big aluminum ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...
