Abstract
A single-inductor-multiple-output (SIMO) DC-DC switching regulator with a current-mode hysteretic control technique having an ultra-fast transient response to suppress cross-regulation is provided. The DC-DC switching regulator includes: at least one power source for providing electrical energy; an inductive energy storage element for accumulating and transferring the electrical energy from the input power source to a plurality of outputs; a main switch for controlling energy accumulation at the inductive energy storage element; a plurality of output switches for controlling energy transfer to each of the plurality of outputs; a freewheel switch coupled in parallel with the inductive energy storage element; and a controller, configured to coordinate the plurality of output switches and the main switch.
