Abstract
A single-inductor multiple-output (SIMO) power converter converts an input voltage into an output voltage and a biasing voltage. The SIMO power converter comprises an inductor and a primary power switch, and a control circuit. The inductor is configured for storing energy from the input voltage. The primary power switch has a control node and is connected between the inductor and the output voltage which powers an output load. The control circuit controls the primary power switch comprising an auxiliary power switch and a driver. The auxiliary power switch is connected between the inductor and the biasing voltage. The driver, powered by the biasing voltage, drives the control node. The biasing voltage determines a signal level at the control node. The primary power switch and the auxiliary power switch are controlled to distribute the energy stored in the inductor to the output voltage and the biasing voltage.
