A method and apparatus is disclosed to regulate an input voltage to provide a regulated output power. The regulated output power may include a smooth direct current (DC) component and an undesired alternating current (AC) component, the smooth DC component being an average of the regulated output power. A buck regulator module of the present invention regulates the smooth DC component to approximate a reference voltage. The buck regulator module additionally replicates the undesired AC component embedded within the regulated output power. A replicated undesired AC component is combined with the regulated output power to reduce the undesired AC component embedded within the output power.
