1. A power converter system comprising:
a switched capacitor power converter;
an always-on power converter; and
a controller,
wherein the power converter system is operable in a first mode of operation in which only the always-on power converter supplies output power and a second mode of operation in which the switched capacitor power converter supplies output power, and
wherein the controller is configured to transition the power converter system from the first mode to the second mode based on a parameter of a current and/or a voltage of output power supplied by the power converter system.
