Zusammenfassung:	A method and apparatus for extending the driving capacity of a power management device are provided. The method involves determining an energy requirement for the operation of a power management device. Next, the method compares the energy requirement for the operation of a power management device with a capability of a first power device. If the energy requirement is greater than the energy requirement of the first power device, the energy is switched to a second power device of higher capacity. The apparatus includes: a first power device; a second power device connected in parallel to the first power device; a first inductor connected to the first power device and a capacitor connected to the first inductor; and a second inductor connected to a second power device and a capacitor connected to the second inductor.
