The system-level value of wide bandgap power semiconductors of higher efficiency, smaller size and weight, and more sustainable energy usage in our power supplies and motor drives is being demonstrated now. Gallium nitride (GaN) power FETs are replacing silicon (Si) power MOSFETs in applications from 48 V to 800 V. Silicon carbide (SiC) is replacing legacy IGBTs in applications … [Read more...] about Practical Realization of GaN’s Capability
For decades, miniaturization has been the trend in the power supply world. Consumers have been demanding more functions from smaller systems with better performance and reliability at lower cost. Such advances are evident in today’s laptops, tablets, smartphones, industrial drives and a host of other consumer and industrial applications. To meet these demands, the power supply … [Read more...] about Driven by Density, Efficiency at Low Cost, Power Integration Reaches New Heights

It is a sad fact that our digital connected world is under constant attack from malicious parties. Most of the time those bad actors are trying to steal money through fraud or extortion (ransomware attacks). Some of those malicious actors though have a bigger goal of attacking or terrorizing a nation by disrupting or crippling critical infrastructure such as power generation, … [Read more...] about White Hot: Is Your Power Supply Hacker Proof?
Over the past decade computers, displays, smart phones and other consumer electronics systems have become thinner while also becoming more powerful. As a result, the market continues to increase its demand for thinner power supply solutions with greater power density. This article examines the feasibility of adopting various non-isolated dc-dc step-down topologies for an … [Read more...] about Meeting the Power and Magnetic Design Challenges of Ultra-Thin, High-Power Density 48 V DC-DC Converters for Ultra-Thin Computing Applications
