TLVR Power Module Supplies 320 A for AI Processors

Why It Matters

The module’s ultra‑compact, high‑current capability enables denser AI server designs, reducing board space and power‑delivery components while boosting efficiency—a critical advantage as data‑center workloads surge.

Key Takeaways

• 320 A peak current in 9×10×5 mm package.
• 2 A/mm² current density, quad‑phase TLVR design.
• Reduces output capacitance requirement up to 50 %.
• Uses OptiMOS‑6 MOSFETs for efficiency, thermal gains.
• Supports both lateral and vertical AI processor power rails.

Pulse Analysis

The relentless growth of artificial‑intelligence workloads is forcing data‑center architects to rethink power delivery. Traditional voltage‑regulation modules (VRMs) struggle to meet the simultaneous demands for higher current, tighter transient response, and smaller footprints. Infineon’s TDM24745T addresses this gap by packing a quad‑phase TLVR solution into a sub‑cubic‑centimeter package, delivering 320 A peak current—enough to power the most power‑hungry GPU cores without resorting to multiple discrete components.

At the heart of the TDM24745T is a trans‑inductor topology that merges magnetics and decoupling capacitors, achieving a remarkable 2 A/mm² current density. This integration not only streamlines board layout but also slashes the required output capacitance by roughly half, directly improving transient response and reducing overall bill‑of‑materials cost. Coupled with Infineon’s OptiMOS‑6 MOSFETs, the module offers superior conduction efficiency and thermal performance, allowing designers to maintain tighter thermal envelopes in dense server racks.

Beyond the silicon, the module fits into Infineon’s broader AI‑server power‑delivery ecosystem, supporting both lateral and vertical power‑rail architectures. This flexibility simplifies the design of next‑generation AI accelerators, where space constraints and power integrity are paramount. As AI inference and training workloads continue to dominate data‑center traffic, solutions like the TDM24745T will become essential enablers for scaling performance while keeping power budgets and cooling requirements in check.
