Abstract: A switched voltage converter may be controlled with load current feedforward control loop in addition to an output voltage feedback loop. The converter includes a first switch device that is controlled to open and close at a selected switching rate with a selected duty cycle. The first switch device is coupled in series with an inductor and conducts current through the inductor while the first switch is closed. A second switch device conducts current from the inductor to an output capacitor and to load while the first switch is open to produce an output voltage and a resulting load current through the load. The load current is measured in a continuous manner and a load current feedforward control signal is generated that is representative of the load current. The switch rate and/or duty cycle of the first switch is adjusted in response to the load current feedforward control signal.
