About XPhase® ArchitectureXPhase® is IR's distributed multiphase architecture that consists of control ICs and phase ICs that communicateusing a simple five-wire bus scheme. Phases can be added or removed without changing the fundamentaldesign. The five-wire analog bus consists of bias voltage, phase timing, average current, error amplifier outputand VID voltage. By eliminating point-to-point wiring between the control and the phase ICs, the five-wire busshortens interconnections, and reduces parasitic inductance and noise. This simplifies PCB layout and gives amore robust design.
