Data center solutions for traditional and AI-driven infrastructure

Expected to increase to 7% of global electricity usage by 2030, data center power demand is one of the most important societal questions to answer. As our world becomes more and more digital, the demand ?for computing - storing and networking will continue to increase. Meanwhile, many data centers will become AI factories - focused on AI training and inferencing. This will impact the power demands and reshape the AI infrastructure, both inside and outside the server rack.

TCO/OPEX and efficiency increases are crucial aspects to consider in this industry, where even a single-digit percentage decrease in electricity purchasing can mean hundreds of thousand of dollars in annual savings for operators. As a leader in power that is committed to decarbonization and digitalization, Infineon is perfectly positioned to help solve this equation, using our mastery of the three main semiconductor technologies, Si, SiC, and GaN, and more than thirty years of experience in power systems. Together, this powerful combination results in higher efficiency, reduced power demand, and cost savings.?

Server Power Supply Units (PSU)

Infineon's solutions leverage Silicon, GaN, and SiC, technologies to enable hybrid solutions, that deliver the best combination of efficiency, power density, and system cost at each stage of the PSU in single and three phase topologies. Typically for the PFC stage, SiC & Si devices are best suited in single phase PSUs, and SiC & GaN are best suited for three phase PSUs. For the DC-DC LLC stage, typically SiC or GaN are best suited.?

Our semiconductor portfolio of power switches along with our gate drivers, digital isolators, aux power and MCU solutions enable single phase PSUs up to 12 kW and three phase PSUs beyond 20 kW+ across a wide range of PSU topologies. Our solutions support the increasing power requirements of next generation AI server racks as they trend from 100 kW today to ~1 MW+ per rack in the future. They achieve an impressive benchmark efficiency of ~98%, all while meeting strict hold-up time requirements. Infineon is the only player able to offer solutions and expertise across all technologies, including a comprehensive selection of packages that ease mechanical design and enable top-side cooling to deal with the challenge of thermals in the PSU.?

A variety of reference designs are available to shorten PSU development effort and time-to-market.

Battery Backup Units (BBUs) and Power System Reliability Monitoring

Due to the length and complexity of modern data center tasks, safeguarding uninterrupted operation is a crucial task.

BBUs are critical for providing a reliable source of power in the event of an outage or grid failure, ensuring continuous operation of AI workloads. Infineon's battery backup unit solutions leverage advanced converter architectures to minimize size and maximize output power capability and efficiency. They are based on a partial power concept and can be customized depending on the battery configuration, enabling efficient, reliable, and scalable power conversion and ensuring uninterrupted operation of these critical facilities. The partial power concept achieves 4-times higher power density and extending power to 12kW+ and beyond, which is not possible with today's state-of-the-art solutions.

Designed to deliver unmatched reliability and uptime for power supplies, our power system reliability monitoring (PSRM) solutions minimize the risk of outages and consequently lower the total cost of ownership (TCO) for servers. By enabling real-time power supply health monitoring and lifetime estimation, PSRM provides valuable insights based on dynamic system parameter logging. These can be used to improve device utilization, maintenance, and the early detection of potential downtimes, enabling proactive measures to prevent them.

Power path protection

Infineon's digital hot-swap controllers provide a wide range of protection and monitoring features including digital SOA control, which is essential in safeguarding against inrush current and fault conditions in high-availability systems. These devices are optimized for AI servers to allow safe insertion and removal of server blades without shutting down the systems, minimizing downtime and maintaining continuous operation of AI workloads. High-precision AFE, such as current and voltage ADCs and PMBus for telemetry, enables accurate monitoring and reporting of the power and energy usage in a typical server rack system. This allows OEMs/operators to remotely monitor each rack individually for a more efficient system operation, thus resulting in energy saving and minimized system downtime. Infineon¡¯s XDP? digital controllers alongside with OptiMOS? LinearFETs with low RDS(on) and strong SOA capability, provide scalable and robust protection.

Our portfolio will soon expand to include eFuses, which integrate Infineon MOSFETs and current and temperature sensors into one package to reduce design time and BOM cost. This will result in simpler designs and smaller footprints.

48 V Intermediate Bus Converter (IBC)

Transforming the electrical flow from the high voltage server PSU into a more manageable lower voltage is primarily the role of the Intermediate Bus Converter, or IBC for short. The specificity of the application, as well as the extremely limited space on accelerator cards and the very high power requirement drives the need for high power density and efficiency. Further, the load dynamics of the accelerator IC can be wide with peak power nearly double the average. As a result, the combination of high power density, efficiency, and peak power is driving tremendous innovation in the power conversion industry.?

Infineon's innovative, proprietary topologies - both regulated and unregulated DC-DC converters - have been successfully integrated into 48 V Intermediate Bus Converter (IBC) solutions on leading AI card platforms. They currently support power levels of up to 1.5 kW, with a roadmap to scale up to 3 kW in the near future. The higher conversion ratios of the IBC, together with OptiMOS? high density dual-phase power modules, are key enablers of high density vertical power delivery (VPD) and reduced TCO within an AI data center.?
