Abstract:
1. A switching converter, comprising: an input end, for receiving an input voltage; N output ends, for outputting N output voltage signals wherein N is a positive integer; an inductor, coupled to the input end for storing energy of the input voltage; a charging switch, coupled to the inductor for controlling a charging path of the inductor according to a charging switch control signal; N output switches, coupled to the inductor for controlling signal transmitting paths between the inductor and the N output ends according to N output switch control signals; a charging/discharging control unit, coupled to the N output ends for generating a charging/discharging control signal according to an inductor voltage signal and the N output voltage signals; an energy distribution control unit, coupled to the N output ends for generating N energy distribution control signals according to the N output voltage signal, wherein the i-th energy distribution control signal relates to the i-th output voltage signal to the N-th output voltage signal, 1≦i≦N; and a logic control unit, for generating the charging switch control signal according to the charging/discharging control signal and the N energy distribution control signals for controlling an on/off state of the charging switch, and generating the N output switch control signals for controlling on/off states of the N output switches, such that the energy of the input voltage stores in the inductor and the energy stored in the inductor distributes to the N output ends.
