Infineon Invests Over €2 Billion in New Frontend Fab

Ally Winning

There was a time where the trend in the semiconductor industry was to move to a fabless strategy. Why bother with the expense of a fab and gaining the expertise in-house to take care of complex manufacturing, when you could easily subcontract to a specialist who’d make your chips cheaply and with higher yields t

Increasing a Power Supply's Hold-Up Time

Chris Maidment, Technical Marketing Manager, TDK Lambda

During a storm, or when equipment is using a common power source shared with large machinery, the nominal AC input voltage may dip for a short period of time. This frequently happens when lightning strikes are in close proximity to a facility, or when large amount of current is drawn during a welding process on

Regulation Efficiency for Data-Intensive Applications

Trey Roessig, CTO & SVP Engineering, Empower Semiconductor

It is estimated that by 2025 the annual size of real-time data in the global ‘datasphere’ will have increased tenfold from the level in 2018, reaching a total of 51 zettabytes. Indeed, driven in part by the pandemic, global internet traffic grew by around 35% in 2020 as a result of rapid uptake of video st

DC-DC Converter Design Basics

John Quinlan BSc, MSc, Strategic Technical Marketing Manager, Murata Power Solutions

This article gives a broad review of the switched-mode topology technology and some commercial implementations. Historically DC-DC conversion utilised a series pass element (transistor) with linear circuitry, resulting in woeful efficiency levels especially if the differential voltage across the series pass el

Increasing Multi-Output Flyback Transformer Efficiencies in Power Supply Applications

Shane O’Connor, Magnetics Application Design Engineer and Kyle Moldenhauer, Magnetics Product Applications and Marketing Engineer at Bourns

Integrated circuits and transistor components of the switch mode power supply (SMPS) already operate at faster switching speeds and higher efficiency than in previous years. Likewise, magnetic components used in SMPS circuit topologies require advanced design and analysis to keep up. A flyback topology with low
