Abstract
Methods and systems of controlling a switched capacitor converter are provided. Upon determining that a voltage across a flying capacitor is above a first threshold, a first current is drawn from a first terminal of the flying capacitor by a first current source, and a second current is provided to a second terminal of the flying capacitor by a second current source. Upon determining that the voltage across the flying capacitor is below a second threshold, the first current is provided to the first terminal of the flying capacitor by the first current source, and the second current is drawn from the second terminal of the flying capacitor by the second current source. Upon determining that the voltage across the flying capacitor is above the second threshold and below the first threshold from the reference voltage, the first and second current sources are turned OFF.
