A method of forming an integrated circuit employable with a power converter. In one embodiment, the method of forming the integrated circuit includes forming a power switch of a power train of the power converter on a semiconductor substrate, and forming a driver switch of a driver configured to provide a drive signal to the power switch and embodied in a transistor. The method of forming the transistor includes forming a gate over the semiconductor substrate, and forming a source/drain by forming a lightly doped region adjacent a channel region recessed into the semiconductor substrate and forming a heavily doped region adjacent the lightly doped region. The method of forming the transistor further includes forming an oppositely doped well within the channel region, and forming a doped region with a doping concentration profile less than the heavily doped region between the heavily doped region and the oppositely doped well.
