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 ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

The point of this guide is to show the latest and greatest in fan control technology on Intel Z270 motherboards and to help you understand what each brand has to offer in their high-end products. I ...

Edit 25/10/19: at 11:15 onwards, Luke discusses the motherboard vrm and power delivery. He has clarified further whether this ...

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 ...

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 ...

Normal fan ports are only 1 amp, so I don't typically like running more than one fan per. That's only 5 watts, after all. Normal fan ports are 12V, not 5V. A lot of 12V fans won't even start at 5V, ...

Linear Technology Corp.’s new LTC3723 push-pull synchronous PWM controller is specifically targeted toward compact and highly efficient isolated power supplies. The LTC3723 controller's basic features ...

Infineon claims to have come up with the industry’s first 16-phase digital PWM multiphase controller which enables currents up to 1000A and higher for next ...

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 ...

The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...
