摘要

Technique in order to make the surge electric current decrease in the electric charge pump. With illustrate execution configuration, as for the switch of 1 or more where the terminal of the flying capacitor is joined to voltage supply, in order to possess variable on resistance, it is constituted. In order the electric charge pump, gain mode to change to a higher gain from a lower gain, when being constituted, the variable resistant switch of 1 or more is formed, in order with time to possess the resistant profile which is decreased. This way, the surge electric current which is fetched from the voltage supply in the outset of the gain switch can be restricted, but low so far there is charge of steady state and on resistance during discharge. Similar technique is offered in order to make the surge electric current from the pie pass switch decrease which joins supply voltage to positive output voltage of the electric charge pump.
