From the Editors Desk (Dec Newsletter)

As 2018 draws to a close, we can remember it not only for the events that occurred this year, but also some of its “anniversaries”. For example, 2018 marked the 40th anniversary of technical milestones such as the introduction of the first cellular mobile phone system by Illinois Bell and the first computer bulletin board system. Closer to the power electronics realm, 1978 also marked the publication of IEEE-555-2, a standard governing power factor in consumer electronics. This standard ushered in an era in which power factor correction (PFC) would become…  Read more»

Advice To Power Supply Designers (Part 2): The High-Performance Semiconductor Vendor Brings Value

by P.S. Wacher, Semiconductor Industry Veteran

In part 1, the author discussed how engineers working at power supply companies can identify the “needy” component vendors, who tend to waste the engineer’s time, compete almost solely on price and don’t offer much in the way of leading technology or service. While it’s important to recognize and avoid such vendors, it’s equally important that designers be able to identify those vendors who do bring value and help the customers design and build better products. In this part 2 article, the author describes the characteristics of these high-performance or preferred vendors and how they work with customers.   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.
