From the Editors Desk (Sep Newsletter)

Designers have multiple reasons for optimizing the transient response of their on-board power converters and voltage regulators. But lately cost, which is always an issue, has come to the fore as key players in the supply chain have driven up the price of capacitors, particularly conductive polymer aluminum solid electrolytic capacitors and high-value multilayer ceramic caps, which find use in voltage regulator circuits. As David Baretich, observed in part 1 of his article on “Optimizing Regulator Output Capacitance,” the rising component cost is making it…  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.
