Infineon IR35411MTRPBF: A 40A Integrated POL Power Module Redefining Power Density

In the relentless pursuit of higher performance and miniaturization in electronics, the power delivery network (PDN) has become a critical bottleneck. Demanding processors, FPGAs, and ASICs require precise, high-current, low-voltage power supplied right at the point-of-load (POL). Addressing this challenge head-on, Infineon Technologies has introduced the IR35411MTRPBF, a fully integrated 40A POL power module that sets a new benchmark for power density and design simplicity.

This module represents a significant leap beyond traditional discrete multi-chip solutions. By encapsulating the PWM controller, high-performance MOSFETs, inductors, and passives into a single, compact 7mm x 11mm x 3.5mm PQFN package, Infineon has effectively eliminated the most complex and space-consuming aspects of power supply design. This high level of integration delivers unmatched power density, enabling engineers to place a 40A power supply incredibly close to the load, minimizing parasitic inductance and improving transient response.

The IR35411MTRPBF is engineered for exceptional electrical performance. It operates over a wide input voltage range of 2.4V to 16V, making it versatile for a multitude of intermediate bus architectures. Its output can be adjusted from 0.3V to 85% of VIN, catering to the low core voltages of modern silicon. Key to its performance is high efficiency, exceeding 90% across much of its load range, which is achieved through optimized synchronous rectification and low-loss internal components. This efficiency directly translates into reduced thermal dissipation, allowing the module to deliver its full 40A capability without external heatsinks in many applications, further saving board space.

For system designers, the benefits are profound. The module drastically reduces the bill of materials (BOM), component sourcing complexity, and design cycle time. What would typically be a lengthy process of selecting, simulating, and laying out a controller, drivers, MOSFETs, and an inductor is reduced to implementing a single component. This integration also enhances reliability, as all internal components are pre-tested and validated to work together seamlessly under a wide range of operating conditions.

Typical applications are found anywhere high-current, low-voltage power is needed with precision and efficiency. This includes advanced data center servers, telecommunications infrastructure, high-end networking routers, and storage systems. It is also an ideal solution for powering FPGAs and GPUs in industrial automation and test & measurement equipment.

ICGOODFIND: The Infineon IR35411MTRPBF is a paradigm shift in power delivery, offering a complete, high-performance 40A POL solution in a minuscule footprint. Its unparalleled integration simplifies the design process, accelerates time-to-market, and provides a reliable, high-density power source for the most advanced digital loads, making it an superior choice for next-generation electronic systems.
