Abstract:
A comparator circuit includes a first comparator, a second comparator, and a logic portion. The logic portion adjust a variable reference voltage input to the second comparator to become close to a reference voltage input to the first comparator, during a period from a time point when reverse current of current flowing in a coil disposed in a switching power supply device is detected in a state where a first comparison signal is output as a comparison signal while the first comparator and the second comparator are operated, until a first predetermined period of time elapses in a state where switching operation of the switching power supply device is stopped (excluding a period from a time point when the reverse current is detected until a second predetermined period of time shorter than the first predetermined period of time elapses).

Claim (Index 18):
A comparator circuit disposed in a nonlinear control type switching power supply device arranged to generate a desired output voltage from an input voltage, the comparator circuit receiving the output voltage or a feedback voltage corresponding thereto as an input signal, the comparator circuit comprising:\n a first comparator arranged to compare the input signal with a reference voltage so as to generate a first comparison signal; a second comparator arranged to compare the input signal with a variable reference voltage so as to generate a second comparison signal; a variable reference voltage generating portion arranged to generate the variable reference voltage; and a logic portion arranged to output one of the first comparison signal and the second comparison signal as a comparison signal, wherein the logic portion is operable to adjust the variable reference voltage such that logical switching timing of the second comparison signal becomes close to logical switching timing of the first comparison signal when switching from a state where the second comparison signal is output as the comparison signal while the first comparator is stopped and the second comparator is operated to a state where the first comparison signal is output as the comparison signal while the first comparator and the second comparator are operated.
