With the increasingly powerful performance of graphics processing units (Gpus), the requirements for board-level power supplies are also getting higher and higher. The Intermediate bus converter (IBC) can convert a 48V input voltage to a lower bus voltage, which is increasingly important for the energy efficiency, power density and heat dissipation performance of AI data centers. Infineon Technologies announced that its OptiMOS™ 6 80V power MOSFET with a compact 5x6 mm² double-sided heat dissipation (DSC) package has been integrated into the IBC level of the AI server platform of a leading processor manufacturer.

Application tests show that its efficiency is approximately 0.4% higher than that of the previously used solution, equivalent to saving approximately 4.3W per kW of load. If it can be extended to the system level, such as server racks or the entire data center, it will bring significant energy-saving effects. For example, promoting this solution in a hyperscale data center with 2,000 racks can save more than 1.2 MWh of energy per hour, which is equivalent to the energy required to charge 25 small electric vehicles. This solution can save costs and reduce carbon footprints for data center operators, and it has significant benefits.

As the demand for AI computing continues to grow, the market demand for efficient power management solutions will also increase accordingly. Infineon's OptiMOS™ 6 80V can meet the growing energy efficiency demands and provide high-performance solutions suitable for AI server IBC. This MOSFET adopts a 5x6 mm² DSC package, offering superior switching performance in a hard-switching topology and enhancing energy efficiency by reducing on-state losses. In addition, this compact package enables dual-sided heat dissipation, which helps improve thermal management and increase power density, which is crucial for AI server environments with limited space.

Infineon offers a wide range of silicon-based power MOSFETs, among which the OptiMOS™ 6 80V is specifically designed to meet the growing demands for performance, efficiency and integration in AI server applications. This product portfolio adopts the latest MOSFET technology and has launched multiple models for different applications. All products have been optimized for different heat dissipation designs and system requirements. Infineon silicon-based power MOSFETs meet the highest quality and protection standards, thus ensuring the reliability of the product, system uptime and power supply stability.

As a leader in the power system field, Infineon masters all three semiconductor-related materials and has launched a wide range of silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) product portfolios.
