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.

The error amplifier amplifies a difference between the voltage signal corresponding to the output voltage of a DC/DC result and a voltage signal of a lower potential among the plurality of reference voltage signals and, based on-the amplified output, carries out the pulse width modulation control. Furthermore, the control circuit includes a circuit for discharging charges corresponding to the output voltage of the DC/DC result when a power supply to the control circuit is turned off. By the constitution, it is possible to easily realize power turn-on/turn-off sequence controls without requiring any special logic circuit, and thus to control rise/fall characteristics of the output voltage without depending on the load.
