IR35212 dual output digital multiphase controller
The IR35212 is a dual loop, digital, multiphase buck controller designed for CPU and DDR voltage regulation, and is fully compliant with Intel® VR13, VR12.5, VR12 & IMVP8.
The IR35212 includes Infineon’s efficiency shaping technology to deliver exceptional efficiency at minimum cost across the entire load range. Infineon’s dynamic phase control adds/drops phases based upon load current. The IR35212 can be configured to enter 1 or 2-phase operation and active diode emulation mode automatically or by command.
The IR35212 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.
Infineon’s unique Adaptive Transient Algorithm (ATA), based on proprietary non-linear control algorithms provides excellent transient response with reduced output capacitance. The controller also supports programmable cycle-by-cycle current limit per phase for superior dynamic current limiting.
