Gallium nitride (GaN): pushing performance beyond silicon
Maximize power density and reliability with our portfolio of GaN devices for every power level
Our family of gallium nitride (GaN)FETs with integrated gate drivers offer the most efficient GaN solution with lifetime reliability and cost advantages. GaN transistors can switch much faster than silicon MOSFETs which offers the potential to achieve lower switching losses. Our GaN transistors are being adopted for a wide range of applications from telecommunications, servers, motor drives, laptop adapters and on-board chargers for electric vehicles.
GaN’s inherent lower gate and output capacitance enables a MHz switching frequency operation which reduces gate and switching losses to increase efficiency.
GaN’s integrated driver enables switching speeds of >150 V/ns, resulting in half the losses compared to discrete GaN FETs. This, combined with our low-inductance package, delivers clean switching and minimal ringing in every power application.
TI GaN-on-silicon process utilizes our 100% internal manufacturing facilities for fabrication, assembly and test, thus leveraging internally-owned capacity and maximized product quality.
Power management is at the center of enabling the continued integration of electronics in our lives. For decades, TI has been at the forefront of developing new process, packaging and circuit-design technologies to deliver the best power devices for your design. Check out our featured GaN devices below, designed to help you address power density.
GaN FETs with integrated driver & protection for power density
GaN FETs have inherently superior performance over traditional silicon FETs, which is enabling engineers to push the boundary in power designs and reach new levels of power density and efficiency. From consumer applications such as AC/DC power supplies all the way up to multi-kW, three-phase converters – GaN is reducing the weight, size and cost of these power designs while also reducing energy consumption. GaN’s high-speed switching is changing the way power systems look today, enabling market trends such as ultra-thin power supplies, motor drive integrated robotics and achieving >200% more power density in next-generation datacenters and 5G rectifiers.
