Abstract

A single-inductor multiple-output buck/boost DC–DC converter that utilizes an energy storage channel to effectively improve the performance in both self-regulation (SR) and cross-regulation (CR) is presented in this article. With the extra channel, the energy storage and distribution method (ESDM) suppresses CR by extending charge control and SR through parallel power delivery. Additionally, the converter facilitates a seamless transition between continuous conduction mode (CCM) and low power mode (LPM) based on load conditions, thereby enhancing load capacity and overall efficiency. The converter is implemented in a standard 0.18-

μ

m 1.8 V/3.3 V CMOS process. Simulation results indicate that the SR of the proposed design is less than 0.056 mV/mA, achieving a 15.9

\times

reduction compared to the conventional charge control method, while CR is less than 0.027 mV/mA, with a 10.7

\times

reduction. The converter achieves a peak efficiency of 92.3% and maintains an efficiency of 88.2% at a light load of 1 mW.

一种单电感多输出降压/升压DC-DC变换器，具有抑制自调节和通过储能通道的交叉调节

本文介绍了一种利用储能通道有效提高自调节（SR）和交叉调节（CR）性能的单电感多输出降压/升压DC-DC变换器。利用额外的通道，能量存储和分配方法（ESDM）通过并联电力输送扩展充电控制和SR来抑制CR。此外，该转换器还可以根据负载情况在连续导通模式（CCM）和低功率模式（LPM）之间无缝转换，从而提高负载能力和整体效率。该转换器采用标准的0.18 μm 1.8 V/3.3 V CMOS工艺。仿真结果表明，该设计的SR小于0.056 mV/mA，比传统充电控制方法降低15.9倍；CR小于0.027 mV/mA，比传统充电控制方法降低10.7倍。该变流器的峰值效率为92.3%，在1 mW的轻负荷下保持了88.2%的效率。
