Abstract
A driving circuit includes a dead-time detecting circuit, a duty-cycle controlling circuit, and a switch controlling circuit. The dead-time detecting circuit is coupled to an output of a power switch set for detecting a switching voltage on the output of the power switch set and accordingly outputting a dead-time detecting signal. The output of the power switch set is coupled to the first end of an inductive load, and the second end of the inductive load provides an output voltage. The duty-cycle controlling circuit is coupled to the second end of the inductive load for generating a set/reset signal according to the output voltage. The switch controlling circuit controls the power switch set to be away from a dead state according to the set/reset signal and the dead-time detecting signal.
