A Wide Output Voltage Range Single-Input-Multi-Output Hybrid DC-DC Converter Achieving 87.5% Peak Efficiency With a Fast Response Time and Low Cross Regulation for DVFS Applications
To improve the power delivery in System-on-Chips (SoCs), this paper proposes a single-input-multi-output (SIMO) hybrid converter to obtain fast response time, low cross regulation, and 87% peak efficiency by using a multi-output hybrid power stage and dual-switching-frequency technique. The multiple-output hybrid power stage improves the conversion efficiency without sacrificing the output voltage range, and the dual-switching-frequency technique enhances the response time and cross-regulation performance. The proposed SIMO hybrid converter achieves 87.5% peak efficiency with an output voltage range from 0.4V to 1.6V for all outputs and a total maximum load current of 450mAAdditionally, it achieves less than 0.01mA/mV cross-regulation and less than 20mV overshoot at full-load step transient response.
