ROHM Unveils Advanced Power Solutions for AI Data Centers with 800 VDC Architecture

ROHM, a leading semiconductor industry player, has released a new white paper detailing optimal power strategies for AI data centers based on the novel 800 VDC architecture. This architecture represents a highly efficient, scalable power delivery system poised to transform data center design by enabling gigawatt-scale AI factories. The white paper outlines comprehensive power solutions, including silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) power devices, and analog IC technologies that maximize device performance. ROHM's solutions aim to support large-scale 800 VDC power distribution across AI infrastructure, enhancing data center efficiency, power density, and sustainability.

Key Takeaways:

• ROHM's power solutions support large-scale 800 VDC power distribution across AI infrastructure, enhancing data center efficiency, power density, and sustainability.
• The 800 VDC architecture significantly enhances power density and sustainability in AI data centers, which is critical for supporting large-scale power consumption.
• Wide bandgap devices, such as silicon carbide (SiC) and gallium nitride (GaN), play an essential role in achieving efficient performance and reducing noise in the 800 VDC system.
• Acquiring novel SiC and GaN power devices is critical for companies looking to adopt 800 VDC architecture in their data centers.
• ROHM's SiC and GaN devices contribute to higher efficiency, reduced noise, and increased power density in AI data centers.
• ROHM's EcoSiC, EcoGaN, and EcoMOS products offer industry-leading performance and are designed to support next-generation AI infrastructure.

Statistics:

• Power demand per rack in AI data centers is rapidly increasing, pushing conventional 48V/12V DC power supply systems to their limits.
• AC-DC conversion in 800 VDC systems can reduce energy expenditure by up to 60% in comparison to using conventional power supply in IT racks.
• ROHM's SiC and GaN devices can improve power density by up to 50% in comparison to traditional solutions.
