About full power solutions for AMD server CPU platforms

Infineon provides a full-power solution for AMD CPU platforms, including our best-in-class, common footprint, digital, multiphase power solutions. Infineon's voltage regulation offering for LV DC-DC processor power combines OptiMOS? integrated POL voltage regulators and OptiMOS? integrated smart power stages or OptiMOS? high density dual- or quad-phase power modules with XDP? digital multiphase controllers for the highest power efficiency, fastest transient response, and most accurate telemetry reporting in the industry. These benefits all result in increased reliability and reduced TCO/OPEX.

Introduction to trans-inductor voltage regulator (TLVR) topology

Infineon offers a trans-inductor voltage regulator (TLVR) solution for high-performance systems with XDP? digital power controllers and OptiMOS? power stages. The TLVR topology utilizes an electrically coupled inductor concept that delivers high-speed transient response even at lower switching frequencies. Infineon¡¯s TLVR solution offers an instant response to dynamic load changes with minimal output capacitance, which reduces the overall solution size and bill of materials (BOM) cost significantly when compared to traditional non-coupled inductor-based designs. Operating the voltage regulator (VR) at lower switching frequencies also significantly boosts overall power conversion efficiency and reduces the total cost of ownership (TCO). Overall, TLVR configuration enables efficient, high-density, and cost-effective power management solutions for high-performance systems.

Solving PDN problems in multiphase LV DC-DC processor power applications with TLVR

The power delivery network (PDN) plays a critical role in meeting the deviation specification in applications requiring multiphase buck converters with high di/dt load steps while having stringent output voltage deviation specifications. Rather than physically moving the multiphase VR close to the load, TLVR is an alternative method that employs transformers with a 1:1 turn ratio in place of the traditional power inductors. There are various advantages of such an architecture and almost no downsides. Download the application note or watch our summary video to find out how the Infineon TLVR solution mitigates the shortcomings of the PDN in multiphase voltage regulation applications and the advantages it brings to a multiphase VR application requiring currents of 200 A to 1000 A with high-dynamic content.

Highest current density dual-phase power modules

Infineon is addressing the escalating power requirements of generative AI factories with its second-generation DC-DC power modules: the TDM2354xD and TDM2354xT OptiMOS dual-phase power modules. These 160 A modules are designed for vertical power delivery (VPD) and set a new standard for the industry with their exceptional current density, electrical, and thermal efficiencies.


Compact and efficient design

The TDM2354xD and TDM2354xT OptiMOS dual-phase power modules feature a highly integrated design, combining two OptiMOS 6 power stages, inductors, and capacitors on a single substrate. This innovative approach enables the deployment of two phases of a multiphase buck regulator in a significantly reduced footprint ¨C 40% smaller than equivalent discrete solutions. By minimizing the area required for power delivery, these modules help optimize the overall design and efficiency of AI systems.


Proprietary design for enhanced performance

Infineon's dual-phase power modules incorporate a proprietary inductor-on-top design, which provides improved thermal and electrical performance. This design enables superior energy efficiency in AI factory applications, making it an ideal solution for data centers and other high-performance computing environments.


High-Performance Power Modules for AI Data Centers

Infineon's OptiMOS? TDM2454xx quad-phase power modules are designed to meet the high power demands of AI data centers, offering a peak current of 280 A. These modules boast the industry's best power density of 2.0 A/mm2, enabling true vertical power delivery (VPD) in a compact 10x9x5 mm package.


The TDM2454xx modules feature industry-leading power density, proprietary magnetics for low-profile VPD, and a footprint optimized for tiling arrays of modules. They also utilize Infineon's robust OptiMOS 6 trench technology and chip-embedded package, providing enhanced electrical and thermal efficiencies.
