Abstract:
The present invention discloses a switching regulator, a control circuit and a control method therefor. The switching regulator comprises an upper gate switch, a lower gate switch, and an inductor connected to a switching node. When a current passing through the upper gate switch or the inductor is lower than a threshold, the lower gate switch is kept OFF until a next cycle, and during the cycle wherein the lower gate switch is OFF, the upper gate switch is turned ON for a period of time.
