Abstract
A power supply driver circuit for providing power to an electronic device includes a switch module, a voltage regulator and a driver module. The switch module receives a control signal and turns on according to the control signal. The voltage regulator receives a first voltage and outputs a second voltage when the switch module turns on. The driver module provides power to the electronic device when the driver module receives the second voltage.
