Molded Power Inductors

By: Carlos Farnos, Dr.-Ing. Efrain Bernal / Editor: Gerhard Stelzer

Higher power requirements and miniaturization expose passives to rising temperatures, increasing the probability of thermal aging. This article explores how to select molded high-current power inductors, which are exposed to high temperatures for an extended time. The constant market demand to increase power density

Achieving High Power Density in a Regulated IBC for Data Center Applications

By: Roberto Rizzolatti, Senior Staff System Innovation Engineer, Christian Rainer, Senior Staff System Innovation Engineer, and Mario Ursino, Staff System Innovation Engineer, all at Infineon Technologies

Introduction Approximately half of the energy consumed in a typical data center is wasted, either during power conversion or through cooling. Given the increasingly urgent requirement to reduce CO2 emissions, this undesirable situation required addressing at both system and converter levels. Research [1] indicates that using 48 V power distribution at the rack level would help to reduce power los

Leveraging High-Z Technology to Cut Solution Power and Size

Sanjay Rajasekhar, Principal Analog Design Engineer, and Arvind Shankar, Staff Design Evaluation Engineer, Analog Devices

Muxed SAR ADCs are commonly used in applications where there is a need to constantly monitor multiple critical variables in the system. In optical communications applications, laser biasing could be monitored via optical power measurement, while EEG/ECG signals from electrodes could be monitored in VSM applications. The

Making Garbage Management Operations Smarter

Tsuyoshi Yamashita (Murata) and Johannes Ollech (Sentinum)

Waste collection is an essential service that municipal bodies need to perform on a regular basis. EU figures (published in 2020) show that each citizen resident in one of its member states on average generated 505kg of garbage waste each year. When applied to the entire population, that clearly constitutes a

Selecting a Low-lq Voltage Reference to Minimize Power Consumption

Masoud Beheshti, Applications and Marketing Director for Voltage References and Supervisors, Texas Instruments, and Jackson Wightman, Texas Instruments

As electronic circuits improve, they become smaller, more precise and more accurate. For a variety of reasons, designers of applications such as industrial automation and medical are under even more pressure to deliver a circuit that is both accurate and has low power consumption. Many applications with thes
