Apparatus are described for a pair of MOSFET power transistors, a MOSFET driver, and an idealized circuit layout utilized in a power stage such as that of a power conversion system. The power stage comprises a pair of MOSFET transistors having substantially identical electrical characteristics and complementary package configurations for simplifying and optimizing the layout of the power stage on a single side or layer of a printed circuit board. The ideal layout effectively avoids parasitic circuit components, minimizes layout area and costs, and permits operation at higher switching frequencies. A new MOSFET transistor pin configuration is also described that is essentially a functional mirror or functional complement of an existing MOSFET transistor pin configuration to provide the complementary package configurations and the optimized PCB layout. A customized MOSFET driver pin configuration further optimizes the power stage layout by arranging the pins of the driver to coordinate with those of the MOSFET transistor pair. |
