Abstract
A driving circuit includes a high-side transistor, a first low-side transistor, a second low-side transistor, and a control circuit. The high-side transistor is coupled between an input voltage and a switch node. The first low-side transistor is coupled between the switch node and a ground. The second low-side transistor is coupled between the switch node and the ground. The control circuit periodically and individually turns on the high-side transistor and the first low-side transistor. After the first low-side transistor is turned off, the control circuit keeps the second low-side transistor on until the high-side transistor is turned on, so as to eliminate the reverse recovery charge of the first low-side transistor.
