Infineon Technologies AG claims the industry’s first trans-inductance voltage regulator (TLVR) module with the launch of its OptiMOS TDM22545T dual-phase power module, addressing the continued need to improve efficiency, power density, and signal integrity in power conversion for high-performance AI data centers. The power module co-packages two smart power stages and two TLVR power inductors to implement two independent synchronous buck converters, and is packaged to optimize for printed-circuit-board layout, heat transfer, driver/MOSFET control timing, and minimal switch node ringing.

The OptiMOS TDM22545T module combines the trench technology power stages with proprietary TLVR inductors to deliver high power density, improved electrical and thermal efficiency, and enhanced signal quality with reduced transients. By leveraging the proprietary TLVR inductance architecture, it minimizes the number of output capacitors, which reduces the overall size of the voltage regulator and lowers bill-of-material costs.
The TLVR inductor offers an ultra-fast transient response to dynamic load changes caused by AI workloads without compromising electrical and thermal efficiency. This translates into increased computing throughput, a robust system design, and reduced total cost of ownership for AI data centers, Infineon said. The inductors are optimized for switching frequencies between 600 kHz to 1.2 MHz.
The new module is compatible with vertical power delivery systems, where power delivery network losses can be reduced up to 50% versus traditional top-side lateral designs, according to Infineon. It supports up to 140 A across both phases in a compact 9 × 10 × 5-mm form factor. The operating temperature range is -40°C to 125°C.
The OptiMOS TDM22545T dual-phase power module is available now on request. The new device will be showcased at Infineon’s OktoberTech Silicon Valley 2025 event, October 16.
