This paper investigates a new control technique for non-isolated single-inductor dual-output (SIDO) buck converters using peak inductor current and differential-mode voltage. The proposed control method applied for SIDO converters operating in continuous conduction mode (CCM) realizes independent control of each output of the SIDO converter to reduce the cross-regulation problem. Simulation results are presented in this paper to verify the proposed control method.
