Abstract

A multi-channel light-emitting diode constant-current-and-light power driving circuit and an electronic device are provided. The circuit includes a power supply unit, a light-emitting unit, a power transistor unit and a control uni. The power supply unit is connected to the light-emitting unit and configured to transmit a voltage signal to the light-emitting unit. The power transistor unit is connected to the light-emitting unit and configured to adjust the current of the light-emitting unit to control the light-emitting unit to be in a constant current state. The control unit is connected to the power supply unit and the power transistor unit, respectively, and configured to monitor the power transistor unit, and adjust the voltage signal through the power supply unit according to a monitored signal to control a voltage value of the power transistor unit to be within a first target value range.
