Design multiphase buck converters with TLVR output filters

Experience the power of TLVR topology in meeting the demands of evolving applications with high current and steep load transients. Historically, transient support heavily relied on the output capacitor bank due to the limiting effect of output filter inductors on the fast current rise from the regulator. TLVR filter configurations, in combination with multiphase buck converters, offer efficient handling of steep load transients while minimizing output capacitance. Achieve fast transient response without compromising critical performance parameters by implementing TLVR topology in the power stage outputs of a multiphase buck regulator. By eliminating the need for large polymeric capacitors, which are known to degrade over time, TLVR improves circuit reliability and contributes to cost savings. Infineon offers a trans-inductor voltage regulator (TLVR) solution for high-performance systems, featuring XDP™ digital power controllers and OptiMOS™ power stages. Explore our advanced TLVR power management solutions for server designs and unlock new possibilities.

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 – 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.
