SWITCHED CAPACITOR POWER CONVERTER CIRCUITRY

Switched capacitor power converter circuitry configured to receive an input voltage and to output an output voltage, the switched capacitor power converter circuitry comprising: a switch network; a flying capacitor coupled to the switch network; and an output capacitor coupled to an output node of the switch network, wherein the switched capacitor power converter circuitry is operable in: a first mode in which the switch network operates at a fixed duty cycle; and a second mode in which the switch network operates at a variable duty cycle based on a predetermined flying capacitor charging threshold and a predetermined flying capacitor discharging threshold.
