    Powering Minds of the Smart
    5V/1A Synchronous Boost with 1A Linear Charger for Power Bank
    DESCRIPTION
    FEATURES
    The ETA9640 is a fully integrated power management unit
    specifically designed for Power Bank, Mobile Charger, Backup
    Battery Charger applications. It consists of a high efficiency
    synchronous step-up boost converter and a linear battery
    charger. The boost can provide up to 1A output current at 5V
    of from a Li-Ion battery input voltage, while the charger can
    charge up to 1A of current from an AC adapter input. The boost
    incorporates circuits that disconnect the input from output,
    during shutdown, short-circuit, output current overloading, or
    other events when output is higher than the input. This not only
    eliminates the need for an external MOSFET and its control
    circuitry to disconnect the input from output, also provides
    robust output overload protection. Using a patent pending
    technique to drive the charger LED indicator, it eliminates the
    need for a micro-controller normally needed in mobile
    chargers. While saving the cost of a micro-controller, since
    the whole units only consumes less than 100uA of quiescent
    current during no load, when considering standby time for one
    charge, it is a much superior solution comparing to the
    traditional solution that needs a micro-controller which
    normally consumes up to 1mA current.
    ETA9640 is available in ESOP8 package.
