The Infineon IR35217 is a dual loop, digital, multi-phase buck controller designed for CPU voltage regulation - it can support up to 8 phases and allows flexible phase assignment between the two loops. The IR35217 can be configured to enter 1 or 2-phase operation and active diode emulation mode automatically or by command. It offers digitally programmable load line thereby eliminating the need for any external load line setting component. The controller is designed to work with integrated and DCR current sense power stages and provides accurate input and output current reporting.

Digitally programmable load line - no external components are needed to set the load line
Infineon Adaptive Transient Algorithm (ATA) on both loops minimizes output bulk capacitors and system cost
Auto-phase detection with PID coefficient auto-scaling
I2C/SMBus/PMBus system interface for reporting of temperature, voltage, current and power telemetry for both loops
