ABSTRACT:
An inrush current restraining circuit (100) includes a power source (Vcc), a charging/discharging circuit (11), a switching circuit (13), a first impedance component (Z1), a second impedance component (Z2), and a controller (10). The charging/discharging circuit is connected to the power source. An input of the switching circuit is connected to the charging/discharging circuit, and an output of the switching circuit is defined as an output of the inrush current restraining circuit. One end of the first impedance component is connected to the power source. The second impedance component is connected between the other end of the first impedance and the switching circuit. The controller is connected a joint of the first impedance component and the second impedance component, for providing a control signal.
