  • Switched mode voltage converter with low-current mode and methods of performing voltage conversion with low-current mode
    Patent number: 7928705
    Abstract: A voltage conversion circuit for a host electronic device includes a buck converter circuit having an input terminal coupled to a first node and having an output terminal coupled to a second node, a switched capacitor voltage converter circuit having an input coupled to the first node and an output coupled to the second node. The buck converter circuit may be configured to be selectively enabled and disabled in response to a control signal, and the switched capacitor voltage converter circuit may be configured to operate when the buck converter circuit is disabled.
    Type: Grant
