Infineon Introduces Power Distribution Board Reference Design to Simplify Evaluation
Infineon Technologies AG has introduced its High-Voltage Power Distribution Board (HV PDB), a comprehensive reference design engineered for next-generation power supply architectures within AI data centers. Announced in Munich, Germany, on October 27, 2026, this platform is designed to enable customers to efficiently evaluate and accelerate the deployment of both ±400 V and 800 V power distribution systems. It specifically addresses the rigorous requirements of high-voltage power supply architectures prevalent in modern AI server racks, offering a holistic system-level approach to power distribution and conversion assessment.
The HV PDB integrates critical functionalities such as high-voltage protection, intermediate bus conversion, power regulation, and telemetry management onto a single board. This integrated design significantly reduces development complexity and shortens time-to-market for designers. Furthermore, it provides valuable insights into system efficiency, protection behaviors, and overall power orchestration, which are crucial for optimizing AI data center operations.
The reference board, with a footprint of 480 × 125 mm², supports both ±400 V and 800 V distribution architectures and is capable of delivering up to 12 kW of output power. It incorporates a blend of Infineon's advanced silicon, silicon carbide (SiC), and gallium nitride (GaN) technologies, particularly in its fully GaN-based high-voltage intermediate bus converter (IBC) modules, which achieve a peak efficiency of up to 98.5 percent. A dedicated MCU board manager, based on the PSOC™ 3, handles telemetry, system monitoring, and intelligent energy management, complemented by PMBus connectivity for system-level coordination.
Beyond its core function, the HV PDB serves as a flexible evaluation platform, allowing developers to either operate the entire power chain or isolate individual stages for detailed architectural studies. Its modular design facilitates the evaluation of alternative IBC modules, EMI filter configurations, and various power management strategies, providing insights into startup sequences, fault behavior, and overall system performance. The board is designed to accommodate industry-standard half-brick high-voltage and quarter-brick medium-voltage IBC power converter modules with standardized pinouts, ensuring compatibility with alternative drop-in solutions.
