Abstract
A circuit includes a zero current detector (ZCD) circuit that senses an inductor current of an inductor and generates signal pulses indicating when an increasing cycle of the inductor current crosses a predetermined current value and when a decreasing cycle of the inductor current crosses the predetermined current value. A sync control provides a control signal specifying one of the signal pulses corresponding to the increasing or decreasing cycle of the inductor current. A sync selector circuit generates a sync pulse representing the signal pulse from the ZCD in response to the control signal. The sync pulse triggers a timing adjustment for a switch device.
