Switching regulator circuit

The utility model discloses a switching regulator circuit for regulating voltage. The circuit comprises a power stage circuit, an error correction circuit, a comparator, a turn-on time generating circuit and a logic control circuit, wherein the error correction circuit receives and feeds back a feedback signal of output voltage of the switch regulator circuit and reference voltage and outputs error correction voltage; an inverting input end of the comparator receives the feedback signal, a non-inverting input end of the comparator receives the difference between the reference voltage and the error correction voltage, and the comparator outputs a comparison signal; the turn-on time generating circuit provides a turn-on time signal; and the logic control circuit receives the comparison signal and the turn-on time signal and outputs a logic control signal to the power stage circuit. The output voltage precision of a switching regulator is improved through the error correction circuit.
