No matter what aspect of electronics design is being discussed, it seems that two subjects are never far away—design tools and test equipment. This is no less true in power electronics. There are always new tools and instruments to talk about, or new advice on how to make better use of existing ones. Time and money may in some cases prevent engineers from acquiring more of these design aids, or becoming more adept in using them. But those who develop them continue to make the case that more engineers could be more productive and avoid schedule busting problems by acquiring, using or learning more about the various design tools and test instruments…  Read more»

Advice To Power Supply Designers (Part 1): Beware The Needy Semiconductor Vendor

by P.S. Wacher, Semiconductor Industry Veteran

Due to the market pressures, U.S. power supply design engineers have aggressive schedules and project deadlines while operating with limited personnel. Therefore it's logical to expect that these customers are now less likely to freely allocate their time to component vendors that do not offer them a compelling advantage/service to support their objectives. In this two-part article series, the author—a longtime industry professional—discusses why companies (and their engineers) need to be careful in determining which semiconductor vendors they meet with and how much time they spend with them. Here in part 1, he explains how engineers can identify the “needy” semiconductor vendor that wastes the customer’s time and offers little beyond low price. While cost pressures may give these vendors a foot-in-the-door with customers, there are serious risks to working with them as the author explains.   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.
