Abstract
A power converter is disclosed. The power converter is configured to provide a regulated output voltage. The power converter includes a first control loop configured to generate a first voltage based on a rate of change of the regulated output voltage. A second control loop is configured to generate a second voltage based on an output current provided by the power converter. An amplifier is configured to generate a third voltage based on the first and second voltages. A control circuit is configured to control the regulated output voltage based on the third voltage.
