There are numerous factors to consider when adding external capacitors to switched-mode power supplies (SMPS). This article will discuss noise, startup, ESR, stability, pre-bias applications, Sense ...

Oscillation and peaking occur primarily when op amps that are not properly compensated are used to drive large capacitive loads. The other results from this situation are lower bandwidth and lower ...

Point of Load (PoL) dc-dc converter modules provide regulated dc power to a wide variety of loads. PoLs are small, efficient and relatively inexpensive, so their ability to provide common powering ...

Existing test solutions aren’t always suitable for the latest improvements in switching regulator technology. Transient load testing can address these inequities. In response to the recent ...

Power management of battery-powered electronic devices is becoming increasingly more important for the microelectronics industry. This white paper details the difference between low dropout (LDO) ...

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 ...

Do you know which decisions are critical to UPS performance and reliability? Applying an uninterruptible power supply (UPS) without considering system issues like output waveform, input voltage ...

Op amps are generally pretty easy to apply, but there are some practical nonideal behaviors you have to keep in mind. [EEforEveryone] takes a test board with some 2X amplifiers on it and — after some ...

Responding to market needs, server technology has rapidly advanced, delivering high-density, highly reliable computing without the massive harmonics issues inherent with older power supplies. One ...

Most load cells on the market use a cantilever outfitted with strain gages to measure loads. Such cells also need a bulky and expensive signal conditioner to make them useful. Engineers at Loadstar ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...
