Texas Instruments (TI) has announced its gallium nitride (GaN) technology and C2000 real-time microcontrollers (MCUs) are being combined with Delta Electronics’ high-efficiency power electronics expertise in the design of an enterprise server power-supply unit (PSU) featuring an 80 per cent improvement in power density with 1 per cent better efficiency, up to 99.2 per cent, for data centre applications, compared to enterprise server power supplies using traditional architecture. A 1 per cent improvement equals 1-megawatt (or 800 households) total cost of ownership savings per data centre.

Delta Electronics chose to work with the company due to its decade-long investment in GaN technology as well as its real-time control solution with C2000 MCUs. The company uses innovative semiconductor manufacturing processes to manufacture GaN-on-silicon technology and integrated circuits (ICs) to help companies such as Delta Electronics create differentiated applications to more efficiently power data centres around the world.

“Our passion at TI is to create a better world by making electronics more affordable through semiconductors, and our GaN technology enables a whole new world of higher efficiency and smaller, more reliable solutions,” Steve Lambouses, vice president for High Voltage Power at TI, said. “In addition to technology investments, TI’s investments in internal manufacturing will allow new technologies like GaN to scale quickly and support customers like Delta.”  

“GaN has crossed the threshold from being a future technology to an immediate, viable option available today for new designs of power supply systems,” Jimmy Yiin, vice president and general manager of the power and system business group at Delta Electronics, said. “This is especially true for server PSUs, for which we are looking to exceed 98 per cent efficiency. The next several years will be exciting because GaN will revolutionise power design and architectures as we know them, which will enable Delta to further cement its position as a leading provider of energy-saving solutions for data centres.”
