Abstract
A power converter comprises at least one output inductor having an input and output terminal. At least one first switch circuit is connected to the input terminal of the output inductor to alternately connect the input terminal to at least one voltage source and to ground. A ripple control circuit is coupled to the output terminal and is adapted to clamp output current of the output inductor to an allowable maximum level in response to an output current overshoot condition produced by a step down in load coupled to the output terminal. The ripple control circuit further comprises an inductor conducting the output current to ground upon the output current overshoot condition.
