Infineon Technologies AG PMIC - Voltage Regulators - DC DC Switching Controllers IR3567AMMS01TRP

The IR3567A is a dual-loop digital multi-phase buck controller designed for CPU voltage regulation, compliant with AMD® SVI1 & SVI2 and Intel® VR12 specifications. It features IR's Efficiency Shaping Technology, which enhances efficiency across a wide load range, and includes Variable Gate Drive to optimize MOSFET gate drive voltage based on real-time load conditions. The controller supports Dynamic Phase Control, allowing it to add or drop active phases according to load current, and can automatically switch to 1-phase operation and diode emulation mode. The IR3567A incorporates an Adaptive Transient Algorithm (ATA) that minimizes the need for output bulk capacitors, contributing to a compact design. It offers extensive fault protection features, including overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP), and overtemperature protection (OTP). The device is equipped with a thermistor-based temperature sensing capability and supports I2C/SMBus/PMBus interfaces for telemetry of temperature, voltage, current, and power. With a switching frequency range of 200kHz to 2MHz per phase, the IR3567A is suitable for high-performance applications, including desktop and notebook CPU voltage regulation and high-performance graphics processors. The product is packaged in a 7x7mm QFN with a 56-pin configuration, making it a compact solution for various designs.
