A switched capacitor voltage converter comprises: an input port; an output port; a first control field-effect transistor (FET) comprising a first terminal coupled to the input port; a second control FET comprising a first terminal coupled to a second terminal of the first control FET; a first tank circuit coupled to the second terminal of the first control FET and to the first terminal of the second control FET; a first high-side sync FET comprising a first terminal coupled to the output port, a second terminal coupled to the first tank circuit; a first low-side sync FET comprising a first terminal coupled to the second terminal of the first high-side sync FET and to the first tank circuit; and a first current sense circuit coupled to the first tank circuit.
