Abstract

Detecting an output voltage of a switching power supply can include: acquiring a first branch current that changes with a first voltage at a first terminal of an inductor of the switching power supply; acquiring a second branch current that changes with a second voltage at a second terminal of the inductor; controlling the first and second branch currents to flow to a same detection terminal; and detecting the output voltage based on a first current flowing through the detection terminal during a first time period, and a second current flowing through the detection terminal during a second time period.
