A simple three-component solution for a switching regulator chip to use for output voltage programming via PWM.

For not using a scope, this method is pretty accurate, and only uses two discrete circuit components (the resistor and the speaker). If you’re ever in a pinch with PWM, this is sure to help ...

INVENTOR EYE Step-By-Step Guide To Making A PWM Motor Controller Posted: February 3, 2025 | Last updated: February 3, 2025 Learn how to create a DC motor speed control circuit using a PWM-based ...

Inspired by NASA aerospace engineering, this project features a plasma thruster, designed to maximize efficiency and increase ...

This KTB2140 current-mode PWM controller can operate as an active ... Protection features include OCP, short-circuit, thermal, under-voltage lockout (UVLO) and over-voltage protection (OVP).

Of course, the standard way of controlling CPU fans these days is with PWM, so he built a circuit which essentially converts the PWM signal from the motherboard into a phantom thermistor.
