The power chip helps AI servers save energy, stay cool, and fit in small spaces, making data centres more efficient and eco-friendly.
As GPUs grow more powerful, so do their power demands, especially at the board level. This makes intermediate bus converters (IBCs), which step down voltages, increasingly important for improving energy efficiency, power density, and thermal performance in AI data centres. Infineon Technologies AG has announced that its OptiMOS 6 80v power MOSFETS, housed in a compact 5×6 mm² dual-side cooling (DSC) package, are now integrated into the IBC stage of an AI server platform from a leading processor maker. Tests show a 0.4% efficiency gain compared to previous solutions, translating to 4.3w saved per kw of load. When scaled across large data centres, this adds up significantly. For example, a 2,000-rack hyperscale data centre could save over 1.2 MWh of energy every hour—enough to charge about 25 small EVS.
With AI workloads surging, efficient power solutions are becoming critical. Infineon’s Optimos 6 80v addresses this with low conduction losses for better switching efficiency and dual-side cooling for improved thermal handling. Its small footprint and thermal design support higher power density—essential for today’s space-constrained AI server setups.
The OptiMOS 6 80V is part of Infineon’s comprehensive lineup of silicon power MOSFETs, built to meet the increasing demands for performance, energy efficiency, and integration in AI server environments. This portfolio includes application-specific variants tailored for different cooling needs and system designs based on the latest MOSFET technology.
Some of the key features of the OptiMOS 6 80V power MOSFETs include:
- Small size (5×6 mm²) with cooling on both sides
- Uses less power, saving 4.3 watts for every 1,000 watts used
- Helps servers run cooler and more efficiently
- Suitable for tight spaces in AI servers
- It can save a lot of energy when used in many servers
- Works well with different cooling setups
- Made with strong quality for long-lasting use
- Part of Infineon’s wide range of power chips
Infineon’s silicon power MOSFETs adhere to the highest standards of quality and protection, ensuring reliable product performance, system uptime, and stable supply.
