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 25):
The comparator circuit according to  claim 23 , wherein the variable reference voltage generating portion further includes an adding portion arranged to add the analog voltage to the reference voltage so as to generate the variable reference voltage.
