  • Methods to reduce current spikes in capacitive DC-DC converters employing gain-hopping
    Patent number: 9906122
    Abstract: A capacitive voltage converter providing multiple gain modes comprising a switched capacitor array having a voltage input and a voltage output. A skip gating control coupled to the switched capacitor array and configured to control a switch resistance value of the switched capacitor array, and to control a switching sequence of the switched capacitor array. An override control coupled to the skip gating control and the switched capacitor array, the override control configured to detect transitions in a gain mode and to modify the switch resistance value of the switched capacitor array and the switching sequence of the switched capacitor array for a finite amount of time following the gain mode transition.
