Power Integrations, a specialist semiconductor firm known for its power-handling chips, announced on Monday that it is collaborating with Nvidia on the tech giant’s initiative to make artificial intelligence (AI) data centres operate at higher voltages for improved energy efficiency. Earlier this year, Nvidia launched a programme with more than a dozen partners to upgrade massive AI data centres—some of which consume as much electricity as small cities—to distribute power internally using 800 volts of direct current (DC) instead of the conventional alternating current (AC). The shift is expected to reduce energy losses and improve overall power efficiency within the data centre infrastructure. Power Integrations, which reported revenue of Rs 34.9 billion (USD 419 million) in its most recent fiscal year, develops gallium nitride (GaN)-based power chips. These components are smaller, more efficient, and better suited to handle the high-power delivery demands of advanced processors such as those designed by Nvidia. While the company has not disclosed a timeline or revenue forecast for its collaboration with Nvidia, Roland Saint-Pierre, Vice President of Product Development at Power Integrations, said that the firm’s experience in producing automotive-qualified GaN devices played a key role in its inclusion on Nvidia’s approved supplier list. “The fact that we are automotive qualified, and already have GaN devices running reliably in vehicles, was eye-opening for them,” Saint-Pierre told Reuters. “This level of rigour and reliability is exactly what’s required for data centres operating at such high voltages.” Nvidia’s supplier list also includes several global competitors, such as Infineon (Germany) and InnoScience (China). The partnership reflects Nvidia’s commitment to building a more energy-efficient data infrastructure, while highlighting Power Integrations’ growing relevance in both automotive and AI-powered computing ecosystems.
