ABSTRACT:
A circuit for, and method of, reducing a preload current required to maintain a duty cycle of an asymmetrical DC/DC converter and a DC/DC converter incorporating the circuit or the method. In one embodiment, the circuit includes an auxiliary inductor, coupled in series with an output capacitor of the converter in an output current doubler thereof, that reduces ripple current in the output current doubler and thereby maintains the duty cycle.
