提出一种高效单电感双输出降压转换器，实现持续功率输出并降低电压波动。
180nm CMOS, 5V输入, 1.8V/3.3V输出, 峰值效率94.9%
单电感双输出降压转换器连续电流高效电压波动
▸创新点1：互补自适应开关调节（CASR）是一种方法创新，通过动态调整开关时序和占空比，优化了双输出之间的功率分配，减少了开关损耗，从而实现了94.9%的峰值效率。
▸创新点2：连续电流平衡（CCB）机制属于电路创新，通过实时监测和调整输出电流，确保两个输出端电流的连续性，显著降低了电压纹波和波动，提升了系统稳定性。
▸创新点3：辅助电流路径被动绕过输出开关是系统创新，通过引入额外的电流路径，减少了开关切换时的能量损耗，进一步提高了整体效率，在全部工作范围内效率均超过90%。
▸创新点4：结合类型-3补偿器（CT-3C）的控制方案，通过优化反馈环路设计，增强了系统的动态响应能力，减少了因ESR和ESL引起的电压波动。
Abstract
This article proposes a single-inductor dual-output
(SIDO) buck converter which always deliveries continuous power
to outputs. The proposed converter has adopted complementary
adaptive-switching regulation (CASR) with a continuous current
balancing (CCB) mechanism and an auxiliary current path to
passively bypass output switches in turn. The proposed converter
and its control scheme can enhance output current continu-
ities and power efficiencies while decreasing voltage ripples
and fluctuations
