ABSTRACT:
A power supply control circuit includes a first switch unit comprising an input terminal to receive a control signal, and a number of second switch units. The second switch units are each connected between an input power source and a power output terminal. The first switch unit controls the number of second switch units to be turned on in response to the control signal being in a first status, so as to control the number of power output terminals to output corresponding power sources. The first switch unit controls the number of second switch units to be turned off in response to the control signal being in a second status, so as to direct the power output terminals to not output the corresponding power sources.
