Abstract:
1. A switching regulator circuit, comprising: an inductor; a first condenser which provides a potential stored therein as a first output of said switching regulator circuit; a second condenser which provides a potential stored therein as a second output of said switching regulator circuit; a switch set including a plurality of switches, said switch set establishing a first path, a second path, and a third path, said first path supplying energy from a DC power supply to said inductor for accumulation of the energy therein, said second path supplying the energy accumulated in said inductor to said first condenser, and said third path supplying the energy accumulated in said inductor to said second condenser; and a timing control circuit which controls said switch set such that said first path and said second path are successively established in an order named within a first cycle for controlling the first output, and said first path and said third path are successively established in an order named within a second cycle for controlling the second output, the first cycle and the second cycle alternating with each other and having respective fixed durations, and the duration of said first path and the duration of said second path being controlled independently of each other.
