Infineon IR3567BMTRPBF: A 6+1 Phase Digital PWM Controller for High-Current CPU and GPU Power Applications
Modern high-performance computing systems, including servers, workstations, and advanced gaming PCs, demand power delivery solutions (PDN) that are not only highly efficient but also incredibly precise and responsive. The Infineon IR3567BMTRPBF is a state-of-the-art digital PWM controller engineered specifically to meet the rigorous power requirements of next-generation CPUs and GPUs.
At the heart of this controller is its 6+1 phase configuration, which provides exceptional flexibility and scalability. The six main phases can be configured to support the core voltage (Vcore) of a high-current processor, while the additional seventh phase is dedicated to powering other system components, such as a GPU's memory or a system agent. This multi-phase architecture is critical for effectively managing thermal dissipation and minimizing output voltage ripple, a key factor in ensuring system stability under heavy and dynamic computational loads.
A defining feature of the IR3567BMTRPBF is its advanced digital control interface. Unlike traditional analog controllers, this digital solution offers unparalleled programmability. Engineers can fine-tune key parameters—including switching frequency, phase shedding, and loop compensation—via an I²C or PMBus interface. This allows for real-time monitoring and adaptive control, optimizing efficiency across the entire load range from idle to full power. The ability to implement adaptive phase shedding significantly boosts light-load efficiency, a crucial metric for improving overall system energy consumption.
Furthermore, the controller integrates comprehensive protection and monitoring features. It provides real-time telemetry for voltage, current, and temperature, safeguarding the processor and the power supply itself from potential damage due to over-current, over-voltage, over-temperature, or under-voltage conditions. This proactive protection is indispensable for the reliability expected in data center and enterprise environments.
Designed for compatibility with Infineon's proprietary PowIRstage® integrated drivers and MOSFETs, the IR3567BMTRPBF forms a complete, optimized power solution. This synergy simplifies design-in, reduces the component count, and maximizes power density, making it an ideal choice for space-constrained applications.
ICGOODFIND: The Infineon IR3567BMTRPBF stands out as a highly integrated and intelligent digital PWM controller that sets a new benchmark for powering demanding processors. Its scalable multi-phase design, precise digital control, and robust suite of protection features make it a superior solution for developing efficient, compact, and reliable power supplies in high-performance computing.
