Abstract

This paper presents a single-inductor dual outputs buck-boost converter with only dual switches. The power distributive control and peak current control are used to improve the performance of load regulation and cross regulation. The proposed design is implemented with a typical 0.25 μm BCD process. The peak efficiency is simulated to be 87.69% at load current of 436 mA. The load regulation is 0.81 and 2.01 mV/mA for 1.0 V and 5.0 V, respectively. Besides, the cross regulation is 0.66 and 3.89 mV/mA for 1.0 V and 5.0 V modes, respectively. Moreover, the maximum load current is 2.234 A.
