Abstract
In one embodiment the present invention includes a switching circuit. The circuit comprises a first transistor, a second transistor, and a boost circuit. The first transistor couples a first power source to a first intermediate node during a first phase of operation and the second transistor couples a second intermediate node to the first intermediate node during a second phase of operation. The boost circuit is coupled to the second intermediate node and provides a second power source by a transferring of energy from the first power source. The transferring of energy includes an inductor receiving energy from the first power source during the first phase of operation and providing a portion of said energy to the boost circuit during the second phase of operation. The boost circuit provides a biasing to enable deactivation of the second transistor during the first phase of operation.
