Infineon DSL70: The Next Generation of High-Efficiency Dual-Slot Low-Voltage Power Modules

The relentless demand for higher performance and greater efficiency in power electronics continues to drive innovation. Addressing this need, Infineon Technologies introduces the DSL70 series, a groundbreaking family of dual-slot low-voltage power modules engineered to set a new benchmark for power density and thermal performance in demanding applications.

This new generation of modules is specifically designed to overcome the limitations of traditional power solutions. By integrating two power stages into a single, compact package, the DSL70 significantly reduces the footprint required on the PCB. This exceptional power density is a critical advantage for space-constrained applications such as high-performance computing (HPC), telecommunications infrastructure, and advanced robotics, where every millimeter counts.

At the heart of the DSL70's innovation is its superior thermal management. The module utilizes Infineon's advanced packaging technology and materials to achieve ultra-low thermal resistance. This allows for more efficient heat dissipation directly from the silicon dies, enabling higher continuous output currents without the need for excessively large heatsinks or complex cooling systems. The result is a system that can operate reliably at higher power levels while maintaining lower overall temperatures, which directly enhances longevity and reliability.

Furthermore, the DSL70 is optimized for switching frequencies that are crucial for modern, fast-response digital power systems. The low parasitic inductance of its package design minimizes switching losses and electromagnetic interference (EMI). When combined with Infineon’s proven OptiMOS™ MOSFET technology, the module achieves unparalleled efficiency across a wide load range. This efficiency translates directly into reduced energy consumption and lower operating costs for end-users.

Ease of use is another cornerstone of the DSL70 design. The dual-slot configuration simplifies the layout for multi-phase voltage regulator modules (VRMs) and POL (Point-of-Load) converters, accelerating time-to-market for design engineers. By reducing the number of discrete components and simplifying the gate drive requirements, it minimizes design complexity and potential points of failure.

ICGOODFIND: The Infineon DSL70 series represents a significant leap forward in power module technology, delivering an optimal blend of miniaturization, thermal superiority, and peak efficiency for the next generation of power-sensitive electronic systems.
