Abstract
One embodiment provides a switching regulator circuit having an overcurrent protection function that enables complete overcurrent protection though simple in configuration. The switching regulator circuit generates an output signal while boosting an input voltage by switching on/off a switching element using a PWM signal. The switching regulator circuit is equipped with a load switch which is connected to the switching element in series and is normally on. And, the switching regulator circuit is further equipped with an overcurrent protection circuit which keeps the load switch off if a current flowing through the switching element is an overcurrent.
