GaN for DC-DC: Gallium Nitride in DC-DC Applications

GaN FETs and ICs are used in DC-DC applications because they offer a combination of high efficiency, compact size, fast switching speeds, and improved thermal performance. These qualities result in energy savings, smaller form factors, higher power densities, and improved overall performance. This makes them the ideal solution for a wide range of applications in various industries, including modern consumer electronics, data centers, electric vehicles, and other power conversion applications.
