摘要： FET's lying on a switching circuit are used to execute a switched capacitor action. The FET's connect a first capacitor to a battery to charge the former at an input power voltage, and after charging, disconnect the first capacitor from the battery but simultaneously connect the first capacitor to a second capacitor to transfer accumulated electric charges to the latter. A control circuit including a comparator and a voltage controlled oscillator monitors an output voltage from the second capacitor and performs a switching control so that the output voltage is maintained at a specific level.
