Some high-frequency radiation issues in power supplies can be resolved by simply adding a common mode inductor or incorporating some RC absorption circuits. However, when it comes to low-frequency ...

A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

This design idea revisits another: “PWM power DAC incorporates an LM317.” Like the earlier circuit, this one implements a power DAC by integrating an LM317 positive regulator into a mostly passive PWM ...

Webasto has been granted a patent for a method to check semiconductor switch faults. By evaluating current measurements or voltage pulses based on duty cycle, faults like short circuits or open ...

The PWM refresh rate of your smartphone’s display is something you probably never think about, and that most people probably have no idea even exists. But, for some, that rate can make or break the ...

I have an NCase M1 and an open air GPU cooler so I use two fans at the bottom of the case to pull in cool air, displacing the hot air exhausted by the GPU. I'm currently using motherboard temperature ...
