Abstract

A closed-loop control system for a DC/DC converter includes a DC/DC converter that receives a first DC voltage and that generates a second DC voltage. The DC/DC converter includes first and second inductances. A control module receives the second DC voltage and generates at least one control signal to one of charge or discharge the first and second inductances. The control module has first and second modes. During the first mode the control module alternately charges one of the first and second inductances and discharges the other of the first and second inductances. During the second mode the control module one of charges or discharges both of the first and second inductances. The control module initiates the second mode when a transient condition occurs in the DC/DC converter. The transient condition is based on one of the second DC voltage and current through an output capacitance in the DC/DC converter.
