Abstract
A detection circuit for a switching converter, whereby: the detection circuit is coupled in parallel with an output capacitor of the switching converter, and is configured to provide a detection branch coupled in parallel with the output capacitor during a first period of a switching cycle, in order to detect an output voltage of the switching converter; and an output voltage detection signal is generated according to the detected output voltage during a second period of the switching cycle. A switching converter can include the detection circuit and an integrated circuit.
