Abstract
Disclosed are a switching regulator and a control circuit and a control method therefor. In one embodiment, the control circuit generates a supplementary signal varying with a state parameter of the power stage in a first mode and keeps the supplementary signal substantially unchanged in a second mode with respect to the value thereof at the moment of switching from the first mode to the second mode so that the supplementary signal at the moment of mode switching is maintained substantially constant, therefore, a steady state can be achieved quickly, and ripples in the output voltage are restrained.
