Classification: CPC H  Y | IPC H

Claim 8:
9. The power converter as claimed in claim 8, further comprising:
a latch-type comparator receiving the output voltage and a reference voltage, comparing the output voltage with the reference voltage, and generating a comparison result signal according to a comparison result of the output voltage and the reference voltage, wherein, whenever the output voltage is less than the reference voltage, a single pulse occurs on the comparison result signal, and each single pulse of the comparison result signal corresponds to one peak of the inductor current; and
a determination circuit receiving the comparison result signal and counting a number of single pulses on the comparison result signal within the predetermined time according to a clock signal to obtain a count value,
wherein the determining circuit determines whether the count value is greater than the predetermined number to generate a control signal to the switched-capacitor conversion circuit, and
wherein in response to the determination circuit determining that the count value is greater than the predetermined number, a switching action of the switched-capacitor conversion circuit is enabled according to the control signal.
