Switch control circuit and backlight driving board

The invention discloses a switch control circuit and a backlight driving board. The switch control circuit comprises a voltage division circuit, a first transistor and a second transistor. The voltage division circuit is provided with an input end and an output end, and the input end is connected with a control signal. The control electrode of the first transistor is connected with the output end, and the input electrode of the first transistor is connected with a power supply voltage. A control electrode of the second transistor is connected with an output electrode of the first transistor, an input electrode of the second transistor is connected with an input voltage, and an output electrode of the second transistor is connected with a voltage output end. According to the invention, the voltage specification of the control signal in the switch control circuit can be adjusted, and the circuit logic disorder caused by the fluctuation of the control signal is avoided. 本申请公开一种开关控制电路以及背光驱动板。开关控制电路包括分压电路、第一晶体管以及第
