Abstract:
A voltage conversion device capable of enhancing conversion efficiency includes a charge pump for generating output voltage linear to input voltage according to the input voltage, a feedback unit for generating a feedback signal according to the output voltage generated by the charge pump, and a regulating unit for outputting and adjusting the input voltage according to the feedback signal provided by the feedback unit, so as to keep the output voltage unchanged.
