Abstract

A voltage regulation circuit can include: a power stage circuit with a single inductor and a plurality of output circuits; each output circuit having an output control switch configured to control a duration of an on time of the output circuit, and an output switch control circuit configured to control the output control switch in accordance with an output voltage sampling signal, a reference current signal that represents an output current of the output circuit, and a clock signal, in order to maintain an output voltage of the output circuit as constant and to decrease interference from load variations of any other of the plurality of output circuits; and where the output control switches are controlled to be on in sequence in each switching period.
