提出了一种高集成度、5电平飞行电容多电平(FCML)DC-DC转换器，它采用扩展纹波注入控制来实现自启动、快速暂态响应和飞行电容电压平衡。该转换器提供5.5V：0.4V-1.2V降压，具有强大的负载和线路抑制功能，峰值效率为92.4%，在13.8：1转换比下效率为>；80%，峰值电流高达1.4A。所有功率器件、自举电容器和控制功能都集成在芯片上；浮动和旁路电容器采用定制组装工艺进行芯片贴合。
This paper presents a highly-integrated, 5-level flying capacitor multilevel (FCML) dc-dc converter that uses augmented ripple-injection control to achieve self-startup, fast transient response, and flying capacitor voltage balance. The converter provides 5.5 V:0.4 V-1.2 V step down with robust load- and line-rejection, peak efficiency of 92.4 % and >80 % efficiency at a 13.8:1 conversion ratio with peak current up to 1.4 A. All power devices, bootstrap capacitors, and control functions are integrated on chip; flying and bypass capacitors are die-attached using a custom assembly process.
