Abstract:
A switched capacitor (SC) power stage includes a first stage circuit with a set of switches coupled in series, a first flying capacitor coupled to a first node between a first and second switch and to a second node between a fifth and sixth switch, a second flying capacitor coupled to a third node between the second and a third switch and to a fourth node between a seventh and eighth switch, and a third flying capacitor coupled to a fifth node between a third and fourth switch and a second terminal coupled to the second node. A control circuit establishes a first configuration of the switches to precharge the first, second, and third flying capacitors to a first voltage, and a second configuration of the switches to precharge the first and second flying capacitors to a second voltage while the third flying capacitor remains charged at the first voltage.
