Abstract
A reconfigurable switched capacitor converter (SCC) topology with nine/ten CMOS switches and two flying capacitors is presented. It is capable of accepting two input sources simultaneously with an input voltage in the range of 1-2.5 V and delivers the output for 15 conversion ratios. The proposed SCC can drive a load current ranging from 10 ?A to 10 mA at an open loop efficiency of >90%. One of the important applications of the proposed converter is the utilisation of photovoltaic (PV) or the combination of PV and other direct current sources. The regulation of the output voltage can be achieved either by changing the voltage conversion ratios or using variable switching frequency.
