The advantages of Power Integration’s PowiGaN gallium-nitride technology for next-generation AI data centers were recently described. At the 2025 OCP Global Summit in San Jose, where NVIDIA gave an update on the 800 VDC design, Power Integrations released a new white paper outlining the possibilities of 1250 V and 1700 V PowiGaN devices for 800 VDC power architectures.
NVIDIA and Power Integrations are working together to speed up the switch to megawatt-scale racks with 800 VDC power.
In the new white paper, Power Integrations’ industry-first 1250 V PowiGaN HEMTs’ performance benefits are described, along with their field-proven reliability and capacity to match the 800 VDC architecture power-density and efficiency requirements (>98%).
The paper additionally demonstrates that a single 1250 V PowiGaN switch outperforms rival 1200 V SiC devices and stacked 650 V GaN FETs in terms of power density and efficiency.
The InnoMux2-EP ICs from Power Integrations is also highlighted in the white paper as a special option for auxiliary power supplies in 800 VDC data centers. The InnoMux-2 device’s SR ZVS operation offers more than 90.3% of 12 V system efficiency in a liquid-cooled, fanless 800 VDC architecture, while its integrated 1700 V PowiGaN switch supports 1000 VDC input voltage.
More than 175 million GaN switches are currently in use in end products ranging from data centers to EVs and fast chargers. Power Integrations is the only company that supplies high-voltage 1250 V and 1700 V GaN switches in large quantities. The company initially introduced GaN ICs in 2018, states its official release.
Leadership Comments
“With rising AI power demands, moving to an 800 VDC input simplifies rack design, makes more efficient use of space and reduces copper usage,” said Roland Saint-Pierre, vice president of product development at Power Integrations. “With rising rack power demands, we see 1250 V and 1700 V PowiGaN devices as ideal choices for main and auxiliary power supplies, delivering the efficiency, reliability and power density required in 800 VDC data centers.”
