A DC-DC power supply control circuit includes: a voltage stabilizing diode, a first resistor, a second resistor, a third resistor, a first triode and a second triode. Two ends of the first resistor are connected with an input end and an enable end of the DC-DC power supply respectively. Two ends of the second resistor are connected with the enable end and a collector of the second triode. A base electrode and an emitting electrode of the second triode are connected with a collector of the first triode and ground respectively. A negative electrode end and a positive electrode end of the voltage stabilizing diode are connected with an output end of the DC-DC power supply and a base electrode of the first triode respectively. Two ends of the third resistor are connected with the base electrode and the ground respectively. An emitting electrode of the first triode is grounded.
