A Switched‐Capacitor Single‐Inductor Multiple‐Output Dual‐Path Hybrid DC–DC Converter With Path‐Sharing Technique

Year: 2025

Type: article

Abstract: ABSTRACT Single‐inductor multiple‐output (SIMO) DC–DC converters face the challenges of large inductor current, discontinuous charge to each output and poor self‐regulation. This design proposes a switched‐capacitor SIMO dual‐path hybrid converter that can reduce the inductor volume and output ripple by taking the advantages of hybrid dual‐path structure. The proposed path‐sharing topology improves the transient response of the in‐transient channel. This work, designed in a 0.18‐µm BCD process, reveals in the simulation that the cross‐regulation is 20 mV/A and the self‐regulation is 87 mV/A with a 1A load step. The simulated peak efficiency is 94.3% and maximum output ripple is 24 mV.
