Infineon Buck Controller 2-Channel 56-Pin QFN Surface Mount 2MHz Switching Frequency IR35201MTRPBF

Infineon IR35201MTRPBF is a high-performance dual-loop digital multi-phase buck controller specifically engineered for complex CPU voltage regulation needs. It features a 56-pin QFN surface mount package measuring 7mm in length and 850μm in height, ensuring compact integration on printed circuit boards.

This buck controller operates at a high switching frequency of 2MHz, enabling efficient power management and conversion. It supports programmable 1-phase or 2-phase operation modes, including active diode emulation technology, which optimizes efficiency during light and very light load conditions.

The device is engineered to comply fully with several major CPU voltage regulation standards, including Intel VR12 Rev 1.7, VR12.5 Rev 1.5, IMVP8 2 Rev 1.2, and AMD SVI2 REV 1.06, making it suitable for cutting-edge computing applications.

Fault protection is comprehensive, covering over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), over-temperature protection (OTP), and a CAT_FLT indicator to ensure robust system safety and reliability.

An advanced IR Adaptive Transient Algorithm (ATA) minimizes output bulk capacitance, reducing overall system costs without compromising performance. Dynamic phase control and automatic power state switching further enhance energy efficiency.

The IR35201MTRPBF offers multiple digital interfaces including I2C, SMBus, and PMBus, enabling detailed system monitoring with telemetry capabilities reporting temperature, voltage, current, and power for both loops.

Operating voltage ranges from 2.9V minimum input to a maximum of 3.63V and the device reliably functions in temperatures from -40°C to 85°C, making it suitable for challenging industrial, computing, and power management applications.
