How does 800VDC power benefit AI data centers?
800VDC power for AI data centers lowers internal transmission losses compared with lower‑voltage AC/DC architectures, enabling higher energy efficiency and denser rack designs. The approach reduces copper usage, simplifies rack power topology, and supports megawatt‑scale GPU racks with improved thermal and reliability characteristics.
What role do Power Integrations’ PowiGaN chips play in this transition?
Power Integrations provides high‑voltage gallium nitride (GaN) switches—marketed as PowiGaN—engineered for the elevated voltages and power densities demanded by modern AI server farms. According to the company’s white paper and statements at the 2025 OCP Global Summit, the 1250V devices exceed 98% efficiency versus conventional 650V GaN FETs and 1200V silicon carbide parts, while integrated 1700V parts enable 1000 VDC input operation with system efficiencies above 90% in fanless, liquid‑cooled 800V architectures.

Power Integrations, headquartered in California, highlighted the PowiGaN roadmap and the new InnoMux 2‑EP integrated circuits at the OCP Global Summit in San Jose. The firm positions the 1250V PowiGaN family as a higher‑efficiency, smaller‑form‑factor alternative that increases power density for both primary and auxiliary supplies in AI racks. The InnoMux 2‑EP ICs incorporate integrated 1700V PowiGaN switches to support higher DC inputs while aiming to preserve system‑level efficiency in demanding thermal environments.
“With rising AI power demands, moving to an 800VDC input simplifies rack design, makes more efficient use of space, and reduces copper usage. We see 1250V and 1700V PowiGaN devices as ideal for main and auxiliary power supplies in high‑voltage data centers.”
