GigaDevice and Navitas unveil Digital Power Joint Lab to accelerate high-efficiency power management deployment
GigaDevice Semiconductor Inc — a fabless supplier of Flash memory, 32-bit microcontrollers (MCUs), sensors and analog products that relocated its headquarters this year from Beijiing to Singapore — has officially launched the Digital Power Joint Lab in collaboration with gallium nitride (GaN) power IC and silicon carbide (SiC) technology firm Navitas Semiconductor Corp of Torrance, CA, USA. By combining GigaDevice’s GD32MCU expertise with Navitas’ advantages in high-frequency, high-speed and highly integrated GaN technologies and its GeneSiC technology leveraging ‘trench-assisted planar’ technology, the collaboration aims to deliver intelligent and high-efficiency digital power solutions for emerging markets such as AI data centers, photovoltaic inverters, energy storage systems, charging infrastructure, and electric vehicles.

Before its official launch, the lab achieved several technical milestones, including 4.5kW and 12kW server power supply solutions and a 500W single-stage PV micro-inverter, addressing the industry’s demand for high-density, high-efficiency power design and demonstrating the combined innovation strength of both companies.
- The 500W single-stage PV micro-inverter solution, powered by GigaDevice’s GD32G553 MCU and Navitas’ GaNFast Bi-Directional power ICs, adopts a single-stage one-to-one architecture, offering high efficiency, low loss, high integration, and cost optimization. Through a hybrid modulation strategy and soft-switching techniques, it achieves over 97.5% peak efficiency, CEC efficiency above 97%, and MPPT efficiency exceeding 99.9%. The single-stage architecture directly converts DC to AC, removing the intermediate DC-DC stage, improving power density while reducing components and system loss. Magnetic integration and GaNFast Bi-Directional power ICs further minimize system size and bill-of-materials (BOM) cost.
- The 4.5kW and 12kW AI server power solutions, developed with GigaDevice’s GD32G553 MCU alongside Navitas GaNSafe ICs, and Gen-3 Fast SiC MOSFETs, target AI servers, conventional servers, and hyperscale data centers. The 12kW model complies with OCP, ORv3 and CRPS standards, through a compact, optimized design, and surpasses the 80 PLUS ‘Ruby’ efficiency benchmark, reaching 97.8% peak efficiency.
With the establishment of the Digital Power Joint Lab, GigaDevice and Navitas aim to further expand their collaboration to accelerate innovation in next-generation digital power systems. The lab will focus on developing comprehensive system-level reference designs and application-specific solutions to enable smarter, greener and more energy-efficient power systems across data centers, renewable energy, and electric mobility.
