Infineon PBL38621/2R2: High-Performance Power Module for Telecom and Industrial Applications

The relentless drive for higher efficiency, power density, and reliability in power systems for telecom infrastructure and industrial equipment demands highly integrated and advanced solutions. Addressing these challenges head-on, Infineon Technologies introduces the PBL38621/2R2, a state-of-the-art power module engineered to set a new benchmark in performance.

This module is a fully integrated DC-DC converter that incorporates critical components—including power switches, inductors, and control circuitry—into a single, compact package. This high level of integration drastically simplifies the design-in process for engineers, reduces the overall bill of materials (BOM), and minimizes the PCB footprint, which is a critical advantage in space-constrained applications. The module delivers a robust output current of up to 20A with a fixed 2.2µH inductor, providing a stable and efficient power rail for advanced ASICs, FPGAs, and processors found in 5G base stations, networking switches, and automated industrial systems.

A cornerstone of the PBL38621/2R2's design is its exceptional power conversion efficiency. Utilizing advanced packaging technology and low-loss components, the module minimizes thermal dissipation. This allows systems to maintain peak performance without the need for complex cooling apparatus, enhancing overall system reliability and longevity. Furthermore, it features a wide input voltage range, making it versatile for use with various intermediate bus architectures commonly employed in its target sectors.

The module is designed with robustness in mind, offering comprehensive protection features such as over-current protection (OCP), over-temperature protection (OTP), and under-voltage lockout (UVLO). These built-in safeguards ensure operational security under fault conditions, protecting both the power module and the sensitive load it powers. This inherent resilience is paramount for mission-critical applications where system uptime is non-negotiable.

ICGOOODFIND: The Infineon PBL38621/2R2 stands out as a superior power solution, offering designers a potent combination of high integration, peak efficiency, and outstanding thermal performance. It effectively accelerates time-to-market for next-generation telecom and industrial equipment by providing a reliable, compact, and easy-to-use power building block.
