摘要

介绍了一种1.8 V集成单电感双输出升压变换器。该转换器采用时复用控制，仅使用一个1 /spl μ l /H的片外电感提供两个独立的电源电压。可以很容易地扩展拓扑结构以提供多个输出。该变换器采用标准的0.5 /spl μ m CMOS n阱工艺制造。在振荡器频率为1mhz时，总输出功率为350mw时，转换效率达到88%。

A 1.8 V single-inductor dual-output switching converter for power reduction techniques

A 1.8 V integrated single-inductor dual-output boost converter is presented. This converter adopts a time-multiplexing control in providing two independent supply voltages using only one 1 /spl mu/H off-chip inductor. The topology could easily be extended to give multiple outputs. The converter is fabricated with a standard 0.5 /spl mu/m CMOS n-well process. At an oscillator frequency of 1 MHz, the conversion efficiency reaches 88% at a total output power of 350 mW.
