Abstract:
A method and system of driving a switched capacitor converter having a plurality of switches. A first driver coupled to a first switch is powered by providing a first reference voltage level VCC to a first supply and a GND reference to a second supply node of the first driver. A second driver coupled to a second switch is powered by providing a unidirectional path between the first supply node of a first driver and the first supply node of the second driver and by keeping OFF the second switch while turning ON the first switch. A third driver coupled to a third switch is powered by providing a unidirectional path between the first supply node of a second driver and the first supply node of the third driver and by keeping OFF the first and third switch while turning ON the second switch.
