Abstract
A DC-DC power converter circuit includes a switched-capacitor circuit, an error amplifier, a latched comparator and a switching controller. The error amplifier adjusts an error amplification signal of the error amplifier in response to an output voltage of the switched-capacitor circuit and a reference voltage. The error amplification signal is then fed to the latched comparator as a comparison reference, resulting in the DC-DC power converter circuit being able to more precisely maintain the output voltage within a predetermined range.
