Abstract
A voltage converter circuit comprises a charge pump circuit, a pulse width modulation (PWM) filter stage circuit, and a control circuit. The charge pump circuit includes multiple switching transistors arranged as a switching bridge including a first bridge portion connected to a second bridge portion; a midpoint capacitor connected to a circuit node coupling the first bridge portion and the second bridge portion; and a first flying capacitor coupled to the first bridge portion and the second bridge portion. The PWM filter stage circuit is coupled to the charge pump circuit and a first input/output terminal and includes a first inductor coupled to the first flying capacitor and the second bridge portion of the switching bridge. The control circuit is configured to control activation of switching transistors of the switching bridge to generate a regulated voltage at the first input/output terminal.
