Abstract
An adaptive power system includes a multi-output reference voltage generator that generates multiple reference voltages; a low-voltage detector that detects a supply voltage and accordingly generates a power detect signal representing relationship between the supply voltage and at least one predetermined threshold; a selector that selects one of the multiple reference voltages according to the power detect signal, thereby outputting a selected reference voltage; a boost control circuit that generates a control signal according to the selected reference voltage; and a boost converter that generates power voltages according to the control signal.
