Abstract
A DC-DC converter uses a switched capacitor arrangement. A filter capacitor is connected between one terminal of the capacitor arrangement and a fixed voltage line and a calibration arrangement is used for setting or enabling selection of the capacitance of the filter capacitor. In this way, a capacitance is added to a terminal of the switched capacitor arrangement. The capacitance value can be chosen or adjusted to keep the DC-DC converter current capability within specification limits.
