Abstract
For use with a power converter having an input, first and second capacitors and first and second switches, a mode selection circuit, having selectable modes of operation, a method of configuring a power converter, and power converter employing the mode selection circuit and method are provided. In one embodiment, the mode selection circuit may function in two modes of operation. In a first mode, based upon an input voltage, the mode selection circuit is adapted to couple the first and second capacitors and the first and second switches together as a half-bridge converter. In a second mode, based upon the input voltage, the mode selection circuit is adapted to couple the first switch and the first capacitor together as a forward-flyback converter and to further couple the second capacitor and the second switch as a clamp thereto. In another embodiment, the first mode is a high voltage mode, in response to a high input voltage and the second mode is a low voltage mode, in response to a low input voltage.
