The company's high frequency, pulse width modulated (PWM) fans eliminate commutation noise by switching their coils with a PWM frequency above the range of human hearing, i.e., beyond 20 kHz. Fan ...

A new line of pulse-width-modulated (PWM) thermal-cooling fans performs at low noise levels by eliminating the power-switching noise of the fan, whose coils switch at 20 kHz. An external PWM signal ...

Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...

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 ...
