Abstract
In one embodiment, a method of controlling a switching regulator can include: obtaining a voltage feedback signal by detecting an output voltage; generating a triangle wave signal by detecting a current flowing through an inductor; generating a first control signal by superimposing the triangle wave signal and the voltage feedback signal; calculating an error between the voltage feedback signal and a first reference voltage, and compensating for the error to obtain a compensation signal; generating a second control signal by comparing the first control signal against the compensation signal; and controlling switching of a power switch in the switching regulator based on the second control signal and a constant time control signal, where an output signal of the switching regulator is maintained as substantially constant.
