You could use a variable resistor, but with large currents you would need a very large resistance. Also, the resistor would be wasting a lot of energy as heat at low speeds. If you could connect a DC ...

The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...

A pulse width modulator (PWM) controller from Microchip Technology allows the introduction of digital control into analog power-supply designs while providing high-speed PWM operation. Designed for ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

San Diego, Calif.—ROHM Electronics has introduced an H-bridge driver IC line, offering designers a simple upgrade path to pulse-width modulation (PWM) speed control using either analog or digital ...

PIC33CK Value Line family of Digital Signal Controllers (DSCs) to provide vital real-time control at a competitive price point. By combining up to 100MHz deterministic processing, high-resolution PWM ...
