技術摘要


A switching regulator includes a first switch; a second switch coupled between the first switch and ground; an inductor coupled to a common node between the first and second switches; a capacitor coupled between the inductor and ground; a controller receiving a disable signal, and generating first and second control signals respectively for the first and second switches; and a crossing detector comparing an auxiliary voltage at the common node with a negative reference voltage to generate a comparison signal, and generating the disable signal based on the first control signal and the comparison signal. The second control signal switches into an inactive state upon the disable signal indicating a reference-crossing of the auxiliary voltage.
