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 19):
The comparator circuit according to  claim 18 , wherein the logic portion checks a magnitude relationship between the reference voltage and the variable reference voltage based on a level of the first comparison signal when a predetermined delay time elapses from a time point when a level of the second comparison signal is changed, in 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, and adjusts the variable reference voltage in accordance with the magnitude relationship.
