Abstract
In one embodiment, a power supply control circuit may include a capacitive boost circuit having only three switches and only one boost capacitor. The capacitive boost circuit may be configured to receive an input voltage and form a first voltage to apply to an inductor. A control circuit of the power supply control circuit may be configured to switch an inductor switch at a first frequency to regulate the output voltage to the desired value, to switch the three switches at substantially the same frequency, and to adjust a duty cycle of the three switches.
