Abstract
A control circuit and control method for a switched capacitor converter (SCC) are provided. An adjustment circuit makes adjustment with a small pull-down current, such that two terminal voltages of a flying capacitor are consistent with an output voltage. Before the SCC works formally for voltage conversion, the two terminal voltages of the flying capacitor are the same as the output voltage.
