90% Peak Efficiency Single-Inductor-Multiple-Output DC-DC Buck Converter with Output Independent Gate Drive Control

📋 论文概要

本文提出了一种输出独立栅极驱动控制的单电感多输出（SIMO）DC-DC buck转换器，解决了宽输出范围（1.2-3.3V）下效率显著下降的问题，实现了90%的峰值效率。

💡 主要创新点

• 提出输出独立栅极驱动控制技术，使功率管栅极驱动电压不随输出电压变化，从而在宽输出范围内保持高效率。
• 通过优化控制时序和功率管尺寸，降低了开关损耗和导通损耗，实现了90%的峰值效率。
