The IR35221MTRPBF from Infineon Technologies is a dual-loop, digital, multi-phase buck controller engineered for CPU voltage regulation. It supports up to 8 phases with flexible assignment between two loops, operating with a supply voltage range of 4.75V to 7.5V.
Key features include compliance with PMBus Rev 1.3 and AVSBus, a switching frequency range from 194 kHz to 2 MHz per phase, and IR's Efficiency Shaping Technology. The controller offers programmable 1- or 2-phase operation for light loads and active diode emulation for very light loads. It also includes IR's Adaptive Transient Algorithm (ATA) to minimize output bulk capacitors and system cost.
This controller is housed in a 32-VFQFN Exposed Pad package and operates within an ambient temperature range of 0°C to 100°C (TJ). It provides comprehensive fault protection including OVP, UVP, OCP, OTP, and CFP, along with cycle-by-cycle current limit. The device utilizes an I2C/SMBus/PMBus system interface for telemetry reporting.
Applications for the IR35221MTRPBF include AVSBus-based systems, Server VR, and Memory VR, making it suitable for demanding power management solutions.
