Traditional power-supply design practices place much emphasis on the selection and placement of the output capacitor to meet tight ripple and noise requirements. Customers are willing to spend money ...

Not all UPS designs are the same. As a result of cost savings in the very competitive UPS market, some designs may not have the highest level of component reliability. Capacitors are an integral part ...

Today’s integrated video filter/driver devices can be designed into video systems (set-top boxes, PVRs, TVs) using a wide range of coupling and clamping configurations, such as input ac- or ...

A power supply’s output capacitors - which are typically ceramic capacitors with values between 100nF and 100μF - cost money, take up space, and, in the case of delivery bottlenecks, can be difficult ...

Switched Capacitor (SC) DC-DC converters are DC-DC switching regulators that use only capacitors and switches to transfer charges between the input and the output. This architecture is an alternative ...

As digital still cameras (DSCs) and mobile phone cameras become more popular, users are demanding higher-quality photos under lower-light conditions. The popular Xenon photoflash is excited by high ...

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 ...

The LTM4644 integrates four separate constant frequency controlled on-time valley current-mode regulators, power MOSFETs, inductors, and other supporting discrete components (Fig. 1). Each of the four ...

Modern active components, such as A/D and D/A converters and operational amplifiers, typically don’t require a negative supply voltage. Op amps in particular are available with rail-to-rail inputs and ...
