Infineon OptiMOS 6 80V MOSFET sets new benchmark in DC-DC power conversion efficiency
As graphics processing units (GPUs) keep getting more powerful, so do the power requirements at the board level. Intermediate bus converters (IBCs) – which convert for example a 48 V input voltage to a lower bus voltage – are becoming more important for energy efficiency, power density, and thermal performance in AI data centres. Infineon announced that its OptiMOS 6 80V power MOSFETs in a compact 5×6 mm² dual side cooling (DSC) package have been integrated into the IBC stage of an AI server platform of a leading processor manufacturer.
Application tests show an efficiency increase of around 0.4 percent compared to previously used solutions, corresponding to a saving of around 4.3 W per kW of load. At the system level, this leads to significant energy savings when scaled across server racks or entire data centres. For instance, scaling this across a hypothetical hyperscale data centre with 2,000 racks would result in over 1.2 MWh in energy savings every hour – the equivalent energy needed to charge 25 small electric vehicles. The implications of this development are substantial, with cost savings and reduced carbon footprint for data centre operators.
As the demand for AI computing continues to grow, the need for efficient power management solutions will increase. Infineon’s OptiMOS 6 80V is well-positioned to meet the growing energy-efficiency demand, offering a high-performance solution for AI server IBCs. Infineon’s OptiMOS 6 80V MOSFET in the 5×6 mm² DSC package offers optimised switching performance in hard switching topologies and high energy efficiency due to lower conduction losses. Additionally, the compact package enables cooling on both sides, which contributes to improved thermal management and higher power density – both crucial in AI server environments with limited space.
