Infineon releases power modules with embedded capacitor layer

Infineon Technologies AG launched the next generation of high-density power modules which play a pivotal role in enabling AI and high-performance computing. Through enhanced system performance and with Infineon’s trademark robustness, the new OptiMOS TDM2454xx quad-phase power modules enable best-in-class power density and total cost-of-ownership (TCO) for AI data center operators.

The OptiMOS TDM2454xx quad-phase power modules enable true vertical power delivery (VPD) and offer the industry’s best current density of 2 Ampere per mm². The modules follow the OptiMOS TDM2254xD and the OptiMOS TDM2354xD dual-phase power modules introduced by Infineon last year and continue to enable superior power density for accelerated computing platforms. In traditional horizontal power delivery systems, power needs to travel across the surface of the semiconductor wafer, which can result in higher resistance and significant power loss. Vertical power delivery minimizes the distance that power needs to travel, thereby reducing resistive losses and enabling increased system performance.

Data centers are currently responsible for two percent of global energy consumption according to the IEA. Fueled by AI, the power demands within data centers are expected to grow by 165% between 2023 and 2030. Continually improving the efficiency and power densities of power conversion from grid to core is vital to enable further advancements in compute performance while reducing TCO.

The OptiMOS TDM2454xx modules are a fusion of Infineon’s robust OptiMOS 6 trench technology, a chip-embedded package for superior electrical and thermal efficiencies, and innovative low-profile magnetic design that continues to push the envelope for performance and quality of VPD systems. Additionally, the OptiMOS TDM2454xx has a footprint that is designed to enable module tiling and improving current flow that enhances electrical, thermal, and mechanical performance. The OptiMOS TDM2454xx modules support up to 280A across four phases with an integrated embedded capacitor layer within a small 10x9mm² form factor. Combined with Infineon’s XDP controllers, they offer a robust power solution with improved system power density.

The OptiMOS TDM2454xx modules are further strengthening Infineon’s unique position in the market with the broadest product and technology portfolio based on all relevant semiconductor materials to power different AI server configurations from grid to core in the most energy-efficient way.
