From the Editors Desk (November Newsletter)

Demand for uninterruptible power supplies (UPSs) in data centers and industrial applications continues to grow with our ever-expanding computing needs. A recent announcement by IHS Markit | Technology predicts that “Edge deployments and cloud and colocation service providers [will] drive [the] global UPS hardware market past $10 billion in 2023.” That’s up from an $8.2 billion market last year, according to the market research firm. With this growth come opportunities to achieve continued improvements in UPS performance, such as higher power supply efficiency… Read more»

The War On FAEs (Part 1): Remembering When FAEs Ruled

by the OT Club

If you’ve been working in the electronics industry for a while, as a user of electronic components, you may have noticed some changes in the levels and quality of service that your semiconductor FAEs provide. If you’ve been working on the other side of the fence, as a semiconductor FAE, then you may be even more keenly aware of these changes. The writers of this article fall into the latter category. As longtime semiconductor FAEs, we have experienced the changes first hand. This article is about the long-term shifts in how semiconductor manufacturers have treated our role as FAEs as a result of the “financialization” of the business.   Read the full story »

The subject of power integrity (PI) concerns the design, analysis and testing of components and systems for the purpose of accurate and reliable delivery of voltage and current from the voltage regulators across power distribution networks (PDNs) to complex and sensitive loads in electronic systems. The challenges of designing modern, high-speed electronic systems are making it increasingly important for engineers to understand PI.
