Abstract
Embodiments of a switching regulator include a single inductor or two inductors connecting an input circuit and a multi-output end circuit that may drive different loads at different respective voltage levels. The input circuit may include a plurality of input switches, and may boost an input voltage or a ground voltage via operation in one of a plurality of selected modes such as a buck mode, a boost mode and a boost-buck mode, to thereby provide an applied voltage to the one or more inductors. Each selected mode may be based on a target voltage for one of a plurality of unit output ends (output load driving sections) in the multi-output end circuit. Output voltages may be monitored and on-times of switches controlled in the multi-output end circuit to maintain the output voltages in respective target ranges.
