Design and Application of the Infineon PEB3265HV5 Power Supply Evaluation Board

The Infineon PEB3265HV5 evaluation board serves as a comprehensive development platform designed to showcase the performance and versatility of the high-voltage half-bridge driver IC (2ED21824S06J) in switch-mode power supplies (SMPS) and other power conversion applications. This board is engineered to simplify the design process, reduce time-to-market, and provide a reliable reference for engineers developing high-efficiency and high-power-density systems.

The core of the board's design is the 2ED21824S06J gate driver, which features high noise immunity and robust performance critical for managing high-voltage MOSFETs or IGBTs in half-bridge topologies. The driver integrates essential protective functions such as undervoltage lockout (UVLO) and interlocking to prevent shoot-through currents, enhancing system safety and longevity. The evaluation board supports an input voltage range suitable for universal mains applications (85 VAC to 265 VAC) and delivers a regulated DC output, demonstrating capabilities in applications like server power supplies, industrial motor drives, and renewable energy inverters.

A key aspect of the board’s design is its emphasis on thermal management and layout optimization. The PCB utilizes a multilayer design with dedicated ground and power planes to minimize EMI and reduce switching losses. Heatsinks and strategically placed thermal vias assist in dissipating heat generated by power semiconductors, ensuring stable operation under full load conditions. Furthermore, the board includes multiple test points for probing critical waveforms, allowing engineers to evaluate switching behavior, loop stability, and efficiency effortlessly.

In practical application, the PEB3265HV5 enables designers to validate performance metrics such as efficiency across load conditions, transient response, and electromagnetic compatibility (EMC). By adjusting component values or feedback network parameters, developers can tailor the board’s operation to specific requirements, accelerating prototype validation and performance benchmarking.
