Abstract: A boost converter and a drive control module thereof are provided. The boost converter includes a inductor, a power switch, a PWM control circuit and the drive control module. The inductor is coupled between the input terminal and the output terminal. The power switch is coupled between a inductor and a ground end. The PWM control circuit is provided to provide the PWM control signal to the gate of the power switch to control the conducting state of the power switch, and the conversion output voltage at the second end. Based on the current load state of the boost converter in operation, the drive control module outputs the gate electronic potential signal to the PWM control circuit according to the input voltage or the conversion output voltage, and the PWM control circuit adjusts the voltage amplitude of the PWM control signal correspondingly.
