Infineon Technologies AG DC DC Switching Controllers IR3566AMIS02TRP

The IR3566AMIS02TRP is a dual-loop digital multi-phase buck controller designed for CPU voltage regulation, compliant with AMD¬Æ SVI1 & SVI2 and Intel¬Æ VR12 specifications. It features IR,Äôs 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. This controller employs an Adaptive Transient Algorithm (ATA) that minimizes the need for output bulk capacitors, contributing to reduced system costs. It offers extensive fault protection features, including over-voltage, under-voltage, over-current, and over-temperature protections, along with thermistor-based temperature sensing. The IR3566A is equipped with an I2C/SMBus/PMBus interface for telemetry of temperature, voltage, current, and power, and supports multiple time programming for easy customization. Operating within a temperature range of -40¬8C to 85¬8C, the IR3566AMIS02TRP is packaged in a 6x6mm, 48-pin QFN format, making it suitable for high-performance applications such as servers, high-end desktop CPUs, and graphics processors.
