Abstract
In accordance with the present invention, a switching converter includes two transistors Qand Qparallel-connected between two terminals. Transistor Qis optimized to reduce the dynamic loss and transistor Qis optimized to reduce the conduction loss. Qand Qare configured and operated such that the dynamic loss of the converter is dictated substantially by Qand the conduction loss of the converter is dictated substantially by Q. Thus, the tradeoff between these two types of losses present in conventional techniques is eliminated, allowing the dynamic and conduction losses to be independently reduced. Further, the particular configuration and manner of operation of Qand Qenable reduction of the gate capacitance switching loss when operating under low load current conditions.
