Infineon Technologies Delivers Advanced Energy-Efficient Power Supply Product Roadmap for AI Data Centers

• Artificial Intelligence (AI) drives growing energy demand in global data centers

• New power supply units (PSUs) based on silicon (Si), silicon carbide (SiC) and gallium nitride (GaN) strengthen Infineon’s leadership in AI power supplies

• World’s first 12Kw PSU gives AI data center operators an edge with improved energy efficiency, power density and reliability

[June 3, 2024, Munich, Germany] The impact of artificial intelligence (AI) has driven the growing energy demand of data centers around the world, highlighting the need to provide efficient and reliable energy supply for servers . Infineon Technologies AG has opened a new chapter in the field of energy supply for AI systems and released a power supply unit (PSU) product roadmap. The roadmap is designed to meet the current and future energy needs of AI data centers while prioritizing energy efficiency.

By achieving higher PSU performance levels, Infineon helps cloud data center and AI server operators reduce system cooling energy consumption. These innovative PSUs reduce power consumption and CO2 emissions, thereby reducing overall operating costs. Powerful PSUs can not only be used in future data centers, but can also replace existing power supply units in servers and improve efficiency.

In addition to the already available PSUs with outputs of 3 kW and 3.3 kW, new 8 kW and 12 kW PSUs will further increase the energy efficiency of AI data centers in the near future. With the 12 kW reference board, Infineon is about to launch the world's first power supply unit that reaches this performance level to power future data centers.

Adam White, President of the Power and Sensor Systems Division at Infineon Technologies , said: “Infineon is powering AI. We are addressing one of the key issues of our time – how to efficiently meet the escalating energy demands of data centers. Infineon’s expertise in integrating three semiconductor materials – silicon (Si), silicon carbide (SiC) and gallium nitride (GaN) – into a single module makes this development possible. As a result, our PSU portfolio not only reflects Infineon’s innovative strength, bringing best-in-class performance, efficiency and reliability to the data center and AI ecosystem, but also consolidates Infineon’s leading position in the power semiconductor market.”

Infineon is also responding to data center operators’ demands for higher system efficiency and less downtime. The rise in server and data center applications has increased the demand for power supplies, resulting in the need to develop power supplies with power ratings ranging from 800 W to 5.5 kW and even higher. This growth is due to the increasing power requirements of graphics processors (GPUs) used to compute AI applications.

Currently, the single-chip power consumption of high-end GPUs is as high as 1 kW, and will reach 2 kW or more by the end of the 2020s, which will increase the total energy demand of data centers. According to the International Energy Agency (IEA), by 2030, data center power consumption will account for 7% of the world's total power consumption, equivalent to India's current power consumption.

Despite the rapidly growing energy demand, the new PSUs from Infineon can contribute to reducing CO2 emissions in AI data centers. This is thanks to the extremely high efficiency of the new PSUs, which minimizes power losses. With an efficiency of up to 97.5%, the new generation of Infineon PSUs meets stringent performance requirements. The new 8 kW PSU supports AI racks with a maximum output power of 300 kW or more. Compared to the current 3 kW PSUs with 32 W/in³, its efficiency and power density are increased to 100 W/in³, further reducing system size and saving operators money.

From a technical perspective, this is made possible by the unique combination of three semiconductor materials: Si, SiC and GaN . This technology helps improve the sustainability and reliability of AI server and data center systems. Innovative semiconductors based on wide bandgap materials such as SiC and GaN are the key to rationally and efficiently using energy to promote decarbonization.

The 8 kW PSU will be available in Q1 2025. For more information on the PSU product roadmap,
