Abstract

For example, a semiconductor device disclosed in the present description is configured to function as a component of a switching power supply, and includes: a current sense signal generator configured to generate a current sense signal by amplifying a sense voltage corresponding to the output current of the switching power supply; a voltage sense signal generator configured to generate a voltage sense signal corresponding to the output voltage of the switching power supply; a selector configured to output as a selected sense signal one of the current sense signal and the voltage sense signal according to a mode switch signal; and an output feedback controller configured to control the driving of the switching power supply based on the selected sense signal.
