Abstract

An output current protection controller includes a comparator circuit and a threshold voltage generator circuit. The comparator circuit compares a current sensing signal with a detection threshold voltage to generate a control signal that controls output current protection of a switching regulator circuit. The current sensing signal is indicative of an output current of the switching regulator circuit. The threshold voltage generator circuit adaptively adjusts the detection threshold voltage according to temperature variation.
