Abstract
A switching regulator for fixing a frequency which includes a power stage circuit, for receiving an input voltage and outputting an output voltage according to an control signal; a reference voltage generator for generating a reference voltage; a comparator for outputting a comparing result according to the output voltage and the reference voltage; a constant-time trigger circuit for outputting the control signal according to the comparing result and a compensating signal; an a frequency compensator for outputting the compensating signal according to the output voltage and a phase signal; wherein the phase signal is corresponding to the magnitude of the voltage across the lower gate switch of the power stage circuit.
