If you ever thought of experimenting with pulse-width modulation, this circuit should get you started nicely. We’ve kept simplicity in mind and used a dual 555 timer, making the circuit a piece of ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

Power supply designers are looking for semiconductor solutions that offer ease of design, a host of protection features and enable power supplies to meet increasingly stringent energy-efficiency ...

[Waggy] submitted this handy device for his entry. It uses several 556 timers to clock a driver chip that drives the mosfet output. If you’re not familiar with PWM – think of it as a six channel motor ...

This file type includes high resolution graphics and schematics. You can build an analog calculator using a pulse-width modulator (PWM) to perform accurate four-quadrant multiplication and division.
