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 ...

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 ...

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 ...

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 ...

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.

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 ...

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, ...
