Available from multiple sources, the UC384X family of current-mode, PWM (pulse-width-modulated) power-supply controllers offers good performance and has spawned a variety of similar ICs. All members ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has him ...

Reducing bill of materials (BOM) cost and footprint area are among the top design considerations for microcontroller (MCU)-based embedded designs. One way to achieve these design goals in 8-bit MCU ...

Deciding between PWM and DC case fans can be confusing, but it’s important for the optimal performance of your computer. In general, PWM fans are quieter, more controllable, and more durable than DC ...

Pulse width modulation has been giving some users problems since the iPhone X. Fortunately, Apple is gearing up to tackle ...
