Gallium nitride (GaN) is redefining power conversion and motion control by enabling higher switching frequencies, greater efficiency, increased power density, and improved thermal performance compared with traditional silicon-based solutions

ST’s GaN Power IC portfolio brings together integrated smart GaNs, GaN drivers, and high-voltage GaN converters to support a broad range of applications, from consumer chargers to industrial and energy systems.

Designed to simplify power-stage implementation while enhancing performance, these solutions help engineers create smaller, lighter, and more efficient systems for demanding high-voltage and high-speed applications.

A complete set of developer resources, including evaluation boards and reference designs, helps accelerate development, reduce design effort, and lower time to market and overall cost.
