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 ...

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

In previous posts, I have introduced several do-it-yourself pwm controller circuits and reviewed several Chinese PWM controller modules. The next step in this post is to share the design of another ...

FAIRCHILD SEMICONDUCTOR has developed the FAN302HL PWM controller for low standby power charger applications. Incorporating mWSaver™technology, the device features patented technologies that allow the ...

As a result, remote control technologies are being widely adopted across various sectors. Among the many components used in ...

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 ...

Edit 25/10/19: at 11:15 onwards, Luke discusses the motherboard vrm and power delivery. He has clarified further whether this is an 8-phase or 16-phase solution: 'you only get 8 true control phases.

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, ...
