摘要： A multi-phase power converter includes a digital ramp pulse modulation controller, a digital constant on-time controller, and a driver stage. The digital ramp pulse modulation controller provides a trigger ramp signal in response to an error signal when the multi-phase power converter is not in a green mode, wherein at least a portion of the digital ramp pulse modulation controller is inactive in the green mode. The digital constant on-time controller provides on-time thresholds and off-time thresholds when the multi-phase power converter is in the green mode. The driver stage provides a plurality of drive signals to a corresponding plurality of power stages in response to the trigger ramp signal when the multi-phase power converter is not in the green mode and to the on-time thresholds and the off-time thresholds when the multi-phase power converter is in the green mode.

摘要： A method and apparatus for estimating capacitor current in a feed-forward control system includes a circuit that conducts a current through an output capacitor to ground and estimates a current magnitude for the current in an output current estimator. The current estimator generates a voltage that corresponds to the estimated current magnitude by creating a voltage drop across an estimator circuit capacitor that equals a voltage drop across the output capacitor, by creating a voltage drop across an output of an RC network of the estimator circuit that equals or is proportional to a voltage drop across the output capacitor due to parasitic inductance and parasitic resistance of the output capacitor. The voltage drop across the output of the RC network of the estimator circuit is proportional to current flowing through the parasitic inductance and resistance of the output capacitor.
