ABSTRACT:
An information handling system includes a power converter having a first switched inductor to supply current to a load. A second switched inductor is inductively coupled to the first switched inductor. A control circuit activates the second switched inductor in response to a change in the power requirements of the load, so as to remove energy stored in the first switched inductor and thereby regulate the output voltage of the power converter when load current is stepped downwards.
