ROHM has published a new white paper exploring advanced semiconductor solutions that enable the next generation of AI data centers powered by the 800 VDC architecture. The paper highlights ROHM’s role as a leading innovator in wide bandgap technologies and system-level power design for large-scale, energy-efficient computing infrastructure.
Developed as part of ROHM’s ongoing collaboration with NVIDIA and other industry partners, the white paper outlines strategies for implementing 800 VDC power distribution across AI data centers—a shift expected to transform data center design by enhancing efficiency, scalability, and sustainability.
The 800 VDC architecture supports the evolution of gigawatt-scale AI factories by significantly improving power density and reducing conversion losses. ROHM’s broad portfolio of silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) power devices, combined with its analog IC expertise, positions the company to deliver optimized solutions for each stage of power conversion.
The paper details how the traditional AC-DC conversion process, typically performed inside server racks, can be relocated to a centralized power rack under the 800 VDC system. This approach simplifies design, improves thermal performance, and allows higher-density configurations for GPU-heavy AI workloads.
ROHM’s EcoSiC™ and EcoGaN™ device families are featured prominently as key enablers of this transition. The EcoSiC™ series provides industry-leading low on-resistance and top-side cooling modules for high-power AI servers, while the EcoGaN™ series integrates GaN performance with ROHM’s proprietary analog IC technologies, including Nano Pulse Control™, enabling fast, precise, and stable high-frequency operation.
Through collaborations with NVIDIA, Delta Electronics, and data center operators, ROHM continues to drive innovation in wide bandgap semiconductors and analog control technologies. Its new white paper underscores the company’s commitment to building efficient, reliable, and sustainable AI data center infrastructure based on 800 VDC power delivery systems.
