Abstract
The control circuit for power supplying includes a driving module and a control module, wherein the driving module includes a first switch, a second switch, a third switch, and a fourth switch. In a first power supply mode, the first switch and the second switch are turned on, and the third switch and the fourth switch are turned off. The load current flows to the ground terminal via the first switch, the inductive load, and the second switch. When the control module sends a switching signal to the driving module, the first switch and the second switch are turned off and the third switch and the fourth switch are turned on, and the load current flows to the high potential terminal via the fourth switch, the inductive load, and the third switch due to the current inertia.
