Gain a comprehensive, in-depth look at computing design expertise through expertly developed brochures created to support efficient power delivery, accelerate development, and help bring your next computing design to deployment with confidence. onsemi presents its system solution guides as practical development resources that help streamline projects and improve design efficiency across multiple application areas.
Designed for high-density server architectures, these solutions combine Si, SiC, and GaN technologies to improve efficiency, increase power density, and optimize power delivery from the grid to the GPU.
They address key challenges such as efficient power conversion, thermal management, scalability, reliability, and system integration, helping engineers design high-performance computing platforms with optimized power delivery and reduced total cost of ownership.
These systems help safeguard critical equipment by filtering power and compensating for short-term grid outages, which is why UPS platforms are widely used in telecommunications, data centers, and other critical facilities. The IEA also notes that UPS batteries and backup generators are essential components for maintaining the high reliability levels required in data centers.
Modern computing systems leverage silicon, silicon carbide (SiC), and gallium nitride (GaN) technologies, combined with gate drivers, power management ICs and Vcores, to achieve higher efficiency, faster switching, and improved overall system performance.
Because electricity is one of the largest operating costs in data centers, higher conversion efficiency directly affects sustainability, cooling demand, and total cost of ownership. onsemi highlights efficiency as central to AI and cloud data center design, and recent IEA analysis shows data center electricity demand rising from about 415 TWh in 2024 toward roughly 945 TWh by 2030 in the base outlook.
As rack power density increases, older low-voltage distribution approaches become less practical because losses rise with higher current. onsemi notes that modern AI infrastructure increasingly pushes toward 48 V distribution and adaptation to 800 V HVDC architectures, while related onsemi materials describe the evolution from 12 V to 48 V and beyond as workloads become more power intensive.
Across the AI data center architecture, common blocks include AC-DC conversion, DC-DC power distribution, hot-swap protection, intermediate bus conversion, multiphase control, smart power stages, smart fuses, and point-of-load buck regulation. onsemi’s AI data center guide specifically describes solutions spanning from the grid to the GPU using Si, SiC, and GaN switching technologies together with power management devices.
Within its AI data center guide, onsemi highlights a 12 kW AI Cloud PSU reference design and states that the design reaches 98% efficiency while delivering high power density and lower cooling demand. The same guide also says the 12 kW power output exceeds competing solutions by about 50% in the referenced comparison.
By protecting power paths during insertion, removal, or fault events, hot-swap stages help improve reliability in dense server environments. Point-of-load regulation is equally important because processors, GPUs, and memory rails require precise local voltage conversion and power management close to the load.
Wide bandgap technologies such as SiC and GaN enable higher efficiency, higher voltage operation, and reduced losses, supporting compact and high-performance power conversion solutions in demanding computing environments.
Through technical guidance, block diagrams, recommended products, practical design advice, and development resources, these guides help engineers shorten development cycles and navigate complex architectures more efficiently. onsemi describes the guides as detailed resources created to streamline project development and enhance design efficiency.
