2022/03/10

Energy-efficient devices are important components for saving resources and protecting the environment. The more efficient the electronics, the longer the battery service life for mobile devices, and in large-scale industrial and server installations with thousands of loads, the energy requirement is clearly reduced. The basis for energy-efficient devices is essentially influenced by the power supply unit. Download the complete Application Note, ANP031, at www.we-online.com/appnotes or click here.

EMC Passive Components for Automotive Applications

Würth Elektronik Watts Up Podcast ·

2022/03/03

Anymore, passive components that are only AEC-Q200 tested are not enough for the use in automotive application. Many more tests are needed for qualification for a good design and high quality component because without electronics, our vehicles would not operate. In this podcast, we discuss a few little design tips using passive components that are adequate enough to pass AEC-Q22 qualifications and complete a reliable automotive design.

Negative Input Resistance of Switching Regulators

Würth Elektronik Watts Up Podcast ·

2022/02/24

Even though a switching regulator may produce a constant output voltage at the end of the development phase, often, designers encounter unpleasant effects, such as unwanted oscillations, at the input. So why does the input of the switching regulator tend to oscillate under certain circumstances? In this podcast, we examine "negative" resistance and come to the understanding that the sign is based on a behavior which can be attributed to transients.

Whisker Growth and Mitigation

Würth Elektronik Watts Up Podcast ·

2022/02/03

A whisker is a crystalline structure of material that appears on tin surfaces. This well-known phenomenon was discovered in the early 1950's, and new legislative actions to avoid lead in electronic components has lead to the return of this whisker problem. These whiskers may reduce the isolation resistance and additional problems arise when the whiskers break and short the printed circuit board or some fine pitch components. In this podcast, we'll discuss some facts about understanding whisker

Influence of a Control Loop by an Output Filter

Würth Elektronik Watts Up Podcast ·

2022/01/13

Output filters are often used for noise suppression, which may have an influence on the control loop. To prevent output power losses, it may be necessary to compensate the control loop. No matter what switching regulator topology is used, as a result of the parasitic series resistor ESR, and the parasitic inductance ESL, of the output capacitor, the output current causes an undesired residual ripple.

Choosing the appropriate components is vital for the efficiency of DC/DC switching regulators with relatively high input and output currents. A high-efficiency switching regulator is market-ready if it, and the end product, comply with all necessary EMC standards; meaning more filters must be included at the input and output to reduce interference. With high input and output currents, it is difficult to find a compromise between the efficiency, size, damping and cost of the filter, and the actual
