Abstract:
A buck converter includes a power switch having one end to which an input voltage is transferred, a synchronous switch connected between the other end of the power switch and the ground, an inductor having an end connected to the other end of the power switch, and a switch control circuit configured to calculate a zero voltage delay time based on at least an ON time of the power switch and a delay time. The delay time is determined based on the inductor and parasitic capacitors of the power switch and the synchronous switch.

Claim (Index 9):
The switch control circuit of  claim 1 , wherein:\n the switch control circuit is configured to control the ON time of the power switch to be constant; the zero voltage delay calculation unit is configured to calculate the zero voltage delay time based on the ON time of the power switch, the delay time, the proportional constant, and a detection voltage peak; and the detection voltage peak is a peak of the detection voltage for each switching period of the power switch.
