Single Inductor Dual Output Hybrid Buck-Boost Converter with Hysteretic Control

A single-inductor, dual-output converter is proposed in this paper. By using flying capacitors, each output is guar-anteed to be provided with continuous current flow in any switching phase, minimizing the output ripples and improving the efficiency. Hysteretic control is used for fastest transient response. The converter is implemented in 130nm technology with wide ranges for both the input and output and its performance (Ripple, Efficiency, Transient Response, etc.) is verified using post layout simulations.
