Abstract
A switched capacitor voltage converter circuit for converting a first voltage to a second voltage includes: an output capacitor; a switched capacitor converter; and a control circuit. The switched capacitor converter includes: a switch circuit including fourth switches; an inductor coupled between the switch circuit and the output capacitor; and a flying capacitor coupled to the switch circuit, wherein the flying capacitor and the output capacitor constitute a voltage divider. The control circuit generates a PWM signal according to the second voltage and generates switch signals according to the PWM signal to control the switch circuit, so as to convert the first voltage to the second voltage. The control circuit decides whether the switched capacitor converter operates in a boundary conduction mode, a discontinuous conduction mode or a continuous conduction mode according to an output current or an output current related signal.
