ROHM Co., Ltd. has announced the integration of its 750V silicon carbide (SiC) MOSFET into a Battery Backup Unit (BBU) for AI server power supplies, marking a significant advancement amid the growing demand for generative AI applications. As AI servers evolve towards higher voltages, the industry is swiftly adopting high-voltage direct current (HVDC) architectures to enhance power efficiency in data centers.
ROHM's SCT4013DLL, a 750V SiC MOSFET, is a critical component in the power supply sector of +400V / -400V architectures utilized by AI servers. The device offers high-temperature resistance with a maximum junction temperature of 175 degrees Celsius, allowing stable operation in BBUs despite increased heat resulting from higher voltage and power density.
The significance of BBUs and Capacitor Units (CUs) is highlighted in high-power environments, where they safeguard rack-level systems against power outages or brief interruptions, thus complementing the transition to HVDC systems. SiC power devices, like ROHM's SCT4013DLL, are expected to be instrumental in these next-generation power systems, thanks to their ability to handle large currents and high voltages with minimal power loss.
In future 800VDC power architectures, the power supplied to the BBU’s battery pack is around 560V, ensuring that ROHM's 750V rated SiC MOSFETs can be seamlessly applied in these configurations as well. This adaptation aligns with the broader industry trend of enhancing power efficiency and promoting more sustainable energy solutions in the tech sector.
With the AI server and data center markets on a trajectory of continued growth, ROHM plans to bolster its development and supply of power devices, not only using silicon carbide but also gallium nitride (GaN) and traditional silicon. The company aims to drive higher power efficiency and contribute to a more sustainable society by integrating these power devices with analog integrated circuits (ICs) and related technologies.
