摘要： For a charge pump, a control circuit switches two or more input voltages to apply to one or more pumping capacitors under auto-sensing control to modulate a maximum pumping voltage as close as to a demanded output voltage to thereby reduce the difference between the maximum pumping voltage and the output voltage for efficiency and thermal improvement of the charge pump. The maximum pumping voltage is produced by mixing the different input voltages and the charge pump may provide more operation modes.
