The system he has come up with is so simple it’s borderline genius. The PWM signal in question is fed through a piezo speaker in parallel with a resistor. The output from the speaker is then ...

PWM stands for Pulse Width Modulation, which is a type of signal used to control electronics. When it comes to PC fans, they run at a constant 12V, which never changes. However, PWM can turn the ...

Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence. They’re so simple, you can buy a class D amp chip for $3, but [George] thought that would be ...

However, most are limited to 8 bits, monopolar (typically 0v to +5v) signal levels, and 5k to 100k resistances with ... Figure 2 The PWMpot’s equivalent circuit where r = switch Ron, P = PWM duty ...

Inside the latest 16-phase power controller from Alpha and Omega Semiconductor and how it helps feed power-hungry GPUs and other AI chips.

KNF has introduced a new series of OEM liquid diaphragm pumps offering high precision and reliability for demanding ...
