Patent ID: 8878504

Claim:
A switching regulator, comprising: an output circuit having a first transistor connected to a higher power supply side, a second transistor connected to a lower power supply side, and a connection node of the first transistor and the second transistor as an output terminal; a switching control unit configured to generate a first switching pulse and a second switching pulse to alternately switch the first transistor and the second transistor according to a load of a load circuit connected to the output terminal via a smoothing circuit; and a first comparator configured to monitor an output voltage generated through the smoothing circuit, and generate a pulse stopping control signal to stop the generation of the first switching pulse and the second switching pulse when the output voltage rises, and to generate the first switching pulse and the second switching pulse when the output voltage drops, wherein the switching control unit further configured to perform a stopping operation to stop the generation of the first switching pulse and the second switching pulse and a switching operation to generate the first switching pulse and the second switching pulse in response to the pulse stopping control signal, and the switching control unit further configured to output a timing control signal to the first comparator, wherein the first comparator is further configured to change the pulse stopping control signal, in response to the timing control signal, to switch from the stopping operation to the switching operation as the load of the load circuit increases.
