Abstract
A voltage conversion circuit and a control circuit thereof are provided. The control circuit includes a voltage selection circuit, a buffer circuit, and a pull-down switch. The voltage selection circuit receives an input voltage and an output voltage, and selects a smaller voltage value as a selected voltage from the input voltage and the output voltage. The buffer circuit receives the selected voltage, and provides the selected voltage as a reference voltage. A control end of the pull-down switch receives an enable signal, so that the pull-down switch is switched on or switched off based on the enable signal. The pull-down switch is switched on based on the enable signal, to pull down a voltage at a control end of a driver switch to the reference voltage and switch off the driver switch.
