Infineon Technologies AG has introduced its roadmap for next-level Battery Backup Unit (BBU) solutions for uninterrupted operations of AI data centers to avoid power outages and the risk of data losses. The comprehensive BBU roadmap includes power solutions from 4 kW up to the world’s first 12 kW battery backup unit. The BBU solutions are designed to deliver highly efficient, reliable, and scalable power conversion in AI server racks, and achieve a power density up to 400 percent higher compared to industry average.
BBUs are essential for AI data centers to provide an uninterruptible power supply and furthermore protect sensitive AI hardware from voltage spikes, surges, and other power anomalies by filtering and conditioning the power that is supplied to the data center equipment. Combined with various best-in-class topologies enabling an increased ease-of-use for customers, the BBU solutions are bolstering Infineon’s leading position in the field of powering artificial intelligence.
“Ensuring an uninterrupted power supply to AI systems is critical for maintaining process continuity and seamless operation,” said Adam White, Division President Power & Sensor Systems at Infineon. “Our energy efficient battery backup units are designed to keep AI servers running smoothly with exceptional performance, flexibility, and efficiency catering to the diverse power levels required by AI servers. By mastering all three relevant semiconductor materials silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) we are confident that Infineon semiconductor solutions will set a new standard in powering AI data centers.”
Downtime or system failures in AI data centers can be extraordinarily costly, with 41 percent of firms interviewed in an ITIC survey from 2024 indicating losses from $1 million to over $5 million per hour of downtime. 35 percent of these failures are attributed to issues with power component quality. To address this, Infineon’s Partial Power Converter (PPC), a semiconductor solution that focuses on improving performance and reliability of power supply systems, stands out as a leading technology for battery backup units.
The intermediate solution, represented by the 5.5 kW BBU, features an Infineon proprietary topology that integrates Si and GaN technologies providing ultra-high efficiency and high-power density. The industry-first 12 kW system combines several 4 kW power converter cards utilizing Infineon’s PSOC™ microcontrollers, 40 V and 80 V OptiMOS™ and EiceDRIVER™ Gate Drivers enabling unparalleled performance and flexibility, achieving a power density four times higher than industry average.
Higher power levels can be attained by paralleling multiple cards on a motherboard, offering ease of scalability and simplified maintenance. If one card fails, the system continues to operate at a reduced capacity, minimizing downtime and ensuring high reliability. This modular approach allows the system to be tailored to specific power requirements without the need for a full system redesign creating substantial customer benefits in performance and reliability.
To further demonstrate the capabilities of the latest BBU technology, Infineon is developing full system demonstrators for its battery backup solutions. These demonstrators will showcase the advantages of the PPC technology in real-world applications offering a clear path forward for next-generation AI data centers.

Alpha and Omega Semiconductor Limited (AOS) announced the release of two state-of-the-art surface mounting package options for its industry-leading high power MOSFET portfolio. Designed to meet the robust packaging requirements for the most demanding applications that require increased performance and reliability, the new GTPAK™ and GLPAK™ packages will first be available on AOS’ AOGT66909 and AOGL66901 MOSFETs respectively. Combining AOS-proven robust MOSFET technology with advanced packaging know-how, these devices provide low ohmic and high current capabilities, critical to reducing the number of parallel MOSFETs needed in high current designs such as in next-generation e-mobility and industrial applications.
The GTPAK offered with the AOGT66909 is a topside cooling package designed with a large exposed pad for more efficient heat transfer. The topside cooling technology transfers most heat to the heat sink mounted on the top exposed pad. This feature allows the GTPAK to offer a more effective thermal dissipation route than going through the PCB board, allowing a lower-cost PCB, such as FR4, to be used.
The GLPAK offered with the AOGL66901 is a gull-wing version of AOS’ successful TOLL package. It is designed using AOS’ advanced clip technology to achieve a high inrush current rating. The GLPAK with clip technology offers very low package resistance and parasitic inductance, improving EMI performance compared to other package types that employ standard wire bonding.
The GTPAK and GLPAK packages feature gull-wing leads, enabling excellent solder joint reliability even for insulated metal substrates (IMS) applications. This gull-wing construction also provides enhanced thermal cycling for IMS boards and other critical applications that must meet higher reliability objectives. AOS MOSFETs in the new GTPAK and GLPAK packages are manufactured in IATF16949-certified facilities and are compatible with automated optical inspection (AOI) manufacturing requirements.
“We are committed to delivering new solutions to help our customers meet or exceed their power performance requirements. By offering our industry-leading MOSFETs in the new robust GTPAK and GLPAK packages, AOS allows designers to select from two state-of-the-art packaging technologies that offer significant performance improvements. Furthermore, the advanced technologies in our AOGT66909 and AOGL66901 MOSFETs will help simplify new designs by reducing the number of devices needed while also providing the necessary higher current capability that makes overall system cost savings possible,” said Peter H. Wilson, Marketing Sr. Director of MOSFET product line at AOS.
