Delta taps TI GaN and controller technology for data centre server power

Delta Electronics is using gallium nitride (GaN) technology and the C2000 real-time microcontrollers (MCUs) from Texas Instruments for an enterprise server power-supply unit (PSU)

The latest design from Delta Electronics boosts efficiency by one percentage point to 99.2 percent. This is the first move into the enterprise market for TI’s GaN chips after the initial focus on automotive power designs.

“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.”

The TI GaN field-effect transistors (FETs) integrate a fast-switching driver, plus internal protection and temperature sensing. Coupled with the C2000 real-time controller, this provides complex, time-critical processing, precision control, and software and peripheral scalability. This also supports  different power-design topologies and highe switching frequencies than silicon to maximise the power efficiency. 

TI’s wholly owned GaN epitaxy and assembly/test footprint enables the company to address tool redundancies, as required.
