An auto‐buck–boost single‐inductor multiple‐output (SIMO) dc–dc converter with duty‐cycle‐constrained comparator control is presented in this Letter. Combined both comparator‐based and duty‐cycle‐constrained controllers enable the dc–dc converter attaining fast transient response and low cross‐regulation (CR). The proposed algorithm is independent of the precision of current sensor and suppresses CR robustly with the proposed tri‐feedback loop control of comparator‐based voltage control, duty‐cycle‐constrained distribution and average current control. The proposed scheme is suitable for auto‐buck–boost SIMO dc–dc converter design for dynamic voltage scaling applications.
