Lots of modern phones use pulse width modulation, or PWM, to manage brightness. But what is PWM, why is it harmful, and what can you do about it? We give you all the details.

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 ...

Alright, I admit that the title is a bit over the top. So, what do I mean by it? I mean that: (1) The application of PWM control to a regulator does not significantly degrade the inherent DC accuracy ...

The NCP1603 from ON Semiconductor combines a power-factor correction control chip and a pulse-width modulation control chip in a single 16-pin SOIC package. This combination simplifies the task of ...

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, ...

Interesting question. Before we could really answer it, we had to read up on pulse width modulation and why virtually all of the OEs now use PWM to control their fuel systems. To be clear, we will ...
