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 »

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.
