A technique is disclosed for more fully utilizing the full voltage range of a battery driven battery output voltage when the battery output voltage is provided through voltage regulation circuitry. More particularly, when the battery output voltage drops to a level that is insufficient to support the desired output of the voltage regulation circuitry, the battery output voltage may be coupled to the voltage output in a manner bypassing at least a portion of the voltage regulation circuitry. In this manner additional voltage range of the battery output voltage may be utilized while still maintaining an output voltage within a desired output voltage range. In one embodiment, such a technique may be utilized in an uninterruptible power supply system.
