Switching regulation circuit

The invention discloses a switching regulation circuit for regulating voltage. The circuit comprises a power level circuit, an error correction circuit, a comparator, a switching-on time generation circuit and a logic control circuit, wherein the error correction circuit receives a feedback signal for feeding the output voltage of the switching regulation circuit back and reference voltage, and outputs error correction voltage; the inverting input end of the comparator receives the feedback signal, and the non-inverting input end of the comparator receives a difference between the reference voltage and the error correction voltage; the comparator outputs a comparison signal; the switching-on time generation circuit provides a switching-on time signal; and the logic control circuit receives the comparison signal and the switching-on time signal, and outputs a logic control signal to the power level circuit. By the error correction circuit, the accuracy of the output voltage of the switching regulation circuit is improved.
