Infineon’s power module integrates trench MOSFETs with TLVR inductor

Infineon Technologies AG is launching the OptiMOS TDM22545T dual-phase power module, the industry’s first trans-inductance voltage regulator (TLVR) module specifically designed for high-performance AI data centers.

The module’s proprietary TLVR inductance architecture minimizes the number of output capacitors, reducing the overall size of the voltage regulator (VR) and significantly lowering material costs (bill of materials; BOM).

The OptiMOS TDM22545T module combines robust trench technology power stages with proprietary TLVR inductors. This results in excellent power density, improved electrical and thermal efficiency, and enhanced signal quality with reduced transients. The inductor design delivers an ultra-fast transient response to dynamic load changes caused by AI workloads without compromising electrical and thermal efficiency. This directly translates into increased computing throughput, a robust system design, and reduced TCO for AI data centers. The new module is also compatible with vertical power delivery (VPD) systems, where power delivery network (PDN) losses can be reduced up to 50% versus traditional top-side lateral designs. It supports up to 140 A across both phases in a compact form factor of 9 x 10 x 5 mm³. Combined with Infineon’s XDP™ controllers, the AI power module family offers the industry’s most robust solution for powering AI data center applications.

The OptiMOS TDM22545T dual-phase power module is available now on request. Further information is available here. The product will also be showcased at Infineon’s OktoberTech Silicon Valley 2025.
