Abstract
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.
