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 ...

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 ...

A Simple PCB that contains a 555 timer for PWM control of various small motors. The design approach taken was to use leftover components from different salvages over the years to see what could be ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

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 Light Intensity Controller Project describes how a simple circuit can be designed to control the intensity of a string of LEDs. The circuit is based on a common 555 timer IC that employs pulse ...

Development of an ASIC with an integrated timing circuit architecture inspired by the well-established 555 timer. The ASIC will be designed to function both as a Clock Generator and a Pulse-Width ...

Abstract: The conventional way to implement a bidirectional converter with boost/buck has been to use two general purpose PWM ICs with a single supply voltage In this case, when one direction mode is ...

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 ...
