Abstract :
A fast-transient, cross-regulation-free, single-inductor multiple-output (SIMO) power converter is proposed. To overcome the inherent drawback of slow load transient response, it employs an adaptive current compensation technique and linear-assisted SIMO architecture, achieving 50.3 ns transient response to 270 mW load change at 500 kHz switching frequency and with 0.35 μm CMOS process. The efficiency reaches the peak of 82.8% at 102 mW and stays above 70% over the entire 300 mW power range.
