Abstract
A dual constant time switching regulator includes: a power circuit including an inductor and at least a power switch for converting an input power to an output power, and a switching control circuit for generating a switch control signal to control the power switch, wherein the switching control circuit includes a comparison circuit for comparing an error amplified signal and a triangle wave signal to generate a comparison result, and a time determining circuit for generating the switch control signal according to the comparison result, wherein after the power switch turns ON, it keeps ON for at least a minimum ON time until the triangle wave signal is higher than the error amplified signal, and wherein after the power switch turns OFF, it keeps OFF for at least a minimum OFF time and until the triangle wave signal is lower than the error amplified signal.
