The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...

Austin, Tex. – Freescale Semiconductor's 4-milliohm MC33981 eXtreme Switch with fast pulse width modulation (PWM) controller, optimized for DC motors, is designed to replace electromechanical relays ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

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 ...
