The voltage booster is a 'true' charge pump. When the output of the 555 is low...

Vishay Intertechnology announced the release of its latest isolation amplifiers, the VIA0050DD, VIA0250DD, and VIA2000SD. These new devices offer enhanced performance for a wide range of industrial, automotive, and medical applications...

In this second part, we’ll turn that semi-decency into something even more respectable, concentrating on minimizing distortion and ignoring the siren song of raw power...

These ultra-simple projects are intended to provide two simple functions without the need for transformers or 'esoteric' parts...

When audio power amplifiers oscillate, the result is often smoke, perhaps with a well-cooked PCB and a side order of fried tweeter. This two-part Design Idea (DI) shows some interesting ways of (mis-)using a common power amp to produce deliberate oscillations of varying qualities...

The circuit adds a soft muting switch with power-up/power-down muting to a line-level audio circuit...

Most mission-critical systems need to be designed for near-zero downtime throughout their useful life. So, if a component of such a system fails or needs updating, it must be replaced without interrupting the rest of the system...

Semiconductor laser diodes are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode...

When talking about standalone single cell battery chargers only one popular name came into my mind that is our versatile Li-Ion/Li-Po TP4056 battery charger...

Many voltage regulator chips, both linear and switching, use the same basic two-resistor network for output voltage programming...
