The best news when you power up a prototype supply board for the very first time is when it not only works, but also runs quiet and cool. Unfortunately, this does not always happen. A common problem ...

The rule of thumb to use a 0.1-µF capacitor on the power pin of a semiconductor device is rapidly fading away. Semiconductor products of today have multiple power pins and voltages. But, it is more ...

Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...
