Power supply circuit, switching regulator, and control circuit and control method thereof
The present invention discloses a switching regulator having a control circuit which includes an error amplifier circuit. The error amplifier circuit compares a feedback signal relating to an output voltage with a reference signal, to regulate the feedback signal to a level of the reference signal. When it is determined that the switching regulator has entered a shutdown procedure, the reference signal gradually decreases so that the output voltage is decreased to a shutdown threshold.
