Abstract
A DC-DC converter includes a power switch and a switching controller. The power switch is repetitively turned on and off for generating an output DC voltage based on an input DC voltage. The switching controller controls operation of the power switch, and includes a slew rate controller to adjust a slew rate of a switch voltage of an electrode of the power switch to vary with time.
