摘要

单电感多输出（SIMO） DC-DC变换器面临着电感电流大、每个输出不连续充电和自调节性差的挑战。本设计提出了一种开关电容SIMO双路混合变换器，利用混合双路结构的优点，可以减小电感体积和输出纹波。所提出的路径共享拓扑结构改善了暂态通道的瞬态响应。这项工作设计在0.18µm的BCD工艺中，仿真结果表明，在1A负载步长下，交叉调节为20 mV/ a，自调节为87 mV/ a。模拟峰值效率为94.3%，最大输出纹波为24 mV。

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

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.
