Abstract: A switching control circuit for a DC-DC converter comprises an input terminal to receive input signals and an output terminal to couple the switching control circuit to a switch of the DC-DC converter. A quasi-static supply path is coupled to the input terminal to receive first signals based on the input signals and coupled to the output terminal to provide output signals to the output terminal based on the input signals. A dynamic supply path is coupled to the input terminal to receive second signals based on the input signals in-phase with the first signals and coupled to the output terminal to provide output signals to the output terminal based on the input signals.
