ABSTRACT:
An integrated circuit employable with a power converter. In one embodiment, the integrated circuit includes a transistor employable as a switch of a power train of the power converter including a gate located over a channel region recessed into a semiconductor substrate. The transistor also includes a source/drain including a lightly doped region located adjacent the channel region and a heavily doped region located adjacent the lightly doped region. The transistor further includes an oppositely doped well located under and within the channel region. The transistor still further includes a doped region, located between the heavily doped region and the oppositely doped well, having a doping concentration profile less than a doping concentration profile of the heavily doped region. The integrated circuit also includes a driver switch of a driver configured to provide a drive signal to the transistor and formed on the semiconductor substrate.
