This article discusses how GaN-based solutions coupled with digital control increase efficiency, shrink the size, and reduce system costs for high density computing applications like ultra-thin laptops and high-end gaming systems. As computers, displays, smartphones and other consumer electronics systems become thinner and more powerful over the past decade, there is increasing demand for addressing the challenge of thinner solutions while extracting more power out of limited space. To address this challenge, the comparative advantages of various non-isolated DC-DC step-down topologies for ultra-thin 48 V – 20 V power solutions that are designed to fit inside a notebook computer or an ultra-thin display are examined.
