CoolGaN™ BDS High-Efficiency 40 V GaN Power Solutions

Infineon Technologies CoolGaN BDS high-efficiency 40 V GaN power solutions are designed for the next-generation of low-voltage designs

Image of Infineon Technologies CoolGaN™ BDS High-Efficiency 40 V GaN Power SolutionsThe Infineon Technologies CoolGaN BDS 40 V G3 family brings the benefits of gallium nitride (GaN) technology to low-voltage power applications, offering significantly reduced switching losses, ultra-fast switching speeds, and improved overall efficiency compared to traditional silicon MOSFETs. These devices are optimized for high-frequency operation, enabling designers to reduce system size while maintaining excellent performance.

The CoolGaN BDS 40 V G3 portfolio is designed to support a wide range of power conversion topologies, providing low RDS(on), low gate charge, and superior figure of merit (FOM). This combination allows for higher power density and improved thermal efficiency, making these devices ideal for compact, high-performance designs.

To accelerate development, Infineon offers evaluation boards and reference designs that help engineers quickly implement and validate CoolGaN-based solutions, reducing time-to-market and design complexity.
