Abstract
A power regulator circuit includes an input node, an output node, a power converter, and a control loop. The power converter is operatively intermediate the input node and the output node and includes a switch and an inductor. The control loop is configured to control operation of the power converter to regulate the flow of electrical power from the input node to the output node. The control loop is operatively connected to the switch and the output node. The control loop takes advantage of a mirror of an error current that is based on an output voltage of the output node. The mirror of the error current modifies a sensed inductor current of the inductor during load transients to speed up a transient response of the power converter.
