Zusammenfassung:The utility model provides a power supply control device for control surging electric current, its protection circuit module who includes a control surging electric current, including the control unit and load switch. The control unit produces the enabling signal. The load switch has first end, second end and control end. Direct current input voltage is received to the first termination of load switch, and the second end is coupled the load control module that has the load capacitance, and the control end is coupled the control unit and is controlled by the enabling signal. When the protection circuit module initial start of control surging electric current, the enabling signal is the continuously pulse width modulation signal of the time of predetermineeing. By this, noise and malfunction because of the surging electric current arouses also can be avoided to the surging electric current in reducible circuit when switch -on.
