This circuit is a fan controller which is using the pulse width modulation (PWM) method. It is tiny (33.78mm x 54.76mm) and easy to build. Functions of the circuit parts are listed below; VR1: 10 K ...

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 ...

This project was created in an attempt to use 22V DC LED bars on a 12V DC source. After locating the MeanWell LDB series of buck boost drivers, I decided I wanted to ad the capability to dim the LEDs, ...

Designed for dual-output dc/dc converters, the IRU3073 PWM controller integrates a low dropout (LDO) controller to enable a second output voltage via a single external MOSFET. It operates with either ...

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 ...

The automotive-grade ISL78226 delivers up to 3.75kW at greater than 95% conversion efficiency, and is able to interleave in a modular master/slave architecture to deliver higher power. November 9, ...

I have a Darlington transistor to keep cool. It is a lovely chunky TIP147 in a TO247 package, attached to a PC heatsink (£6 from ebay) to get the heat out. PC heatsinks are great as they often include ...
