TI and Delta Electronics for energy-efficient server power supplies for data centers

Texas Instruments (TI) 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% improvement in power density with 1% better efficiency — up to 99.2% — for data center applications, compared to enterprise server power supplies using a traditional architecture. A 1% improvement equals 1-megawatt (or 800 households) total cost of ownership savings per data center, according to Energy Innovation.

“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,” said Steve Lambouses, vice president for High Voltage Power at TI. “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.”

“Delta’s long-term focus on reducing mankind’s carbon footprint through energy-efficient products and solutions entails long-term collaboration with industry leaders such as TI in regards to next-generation technologies. GaN has crossed the threshold from being a future technology to an immediate, viable option available today for new designs of power supply systems,” said Jimmy Yiin, vice president and general manager of the Power and System Business Group at Delta Electronics. “This is especially true for server PSUs, for which we are looking to exceed 98% efficiency and 100 W/inch3 of power density. The next several years will be exciting because GaN will revolutionize 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 centers and other major applications.”
