From the Editors Desk (March Newsletter)

This year’s APEC conference, which was to be held next week in New Orleans, has fallen victim to concerns about the COVID-19 virus and has been cancelled—more or less at the 11th hour. For the many who would have attended, this is a lost opportunity to present and learn about the latest R&D and trends in power electronics, to see the latest power products, take tutorials, catch up with colleagues and start dialogues with others in the field… Read more»

The War On FAEs (Part 2): New Management Brings Benign Neglect
 

by the OT Club

In part one of this series, we recounted the heyday of the semiconductor FAEs (field applications engineers), which started in the late 60s and lasted into the 90s. During this time, companies treated their FAEs like kings, encouraging and supporting them in all their efforts to assist customers, and valuing their input on market requirements when defining new products. We also contrasted the work conditions for semiconductor FAEs during the good times with those that exist today to highlight how much the role of the FAE has changed. But how and why did the FAE role change so radically? Here in part 2 we attempt to answer that question by discussing the period when companies began to question the value of their FAEs and started cutting back on the support they were given.   Read the full story »

POWER INTEGRITY INSIGHTS
 

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.
