    DESIGN IDEAS L USB Compatible Li-Ion Battery
    Charger and Dual Buck Regulators
    in a Single 3mm Г— 3mm QFN
    by Aspiyan Gazder Introduction
    Manufacturers of handheld devices
    such as MP3 players are always looking to reduce system size and cost,
    even as they increase performance
    and functionality. The only way to do
    so is to integrate functions at the IC
    level. For applications powered from
    a single Li-Ion cell, the LTC3559
    provides a single chip solution that
    charges a Li-Ion cell while efficiently
    generating two supply voltage rails to
    power the device.
    The LTC3559 is a USB compatible
    battery charger and two monolithic
    synchronous buck regulators integrated into a low profile 3mm Г— 3mm
    16-lead QFN package. The battery
    charger has all the features that a
    stand alone battery charger might
    offer, such as an NTC input for temperature qualified charging, internal
    timer termination and bad battery ...

    by Sam Nork
    Less Than 20mm2
    Introduction
    The quickest way to build an efficient
    power system for a battery-powered
    portable application is to use an
    IC that combines all power control
    functions into a single chip, namely a
    Power Management Integrated Circuit
    (PMIC). PMICs seamlessly manage
    power flow from various power sources
    (wall adapters, USB and batteries) to
    power loads (device systems and the
    charging battery), while maintaining
    current limits where required (such
    as that specified for USB). To this
    end, PMICs typically feature built-in
    PowerPathв„ў control, DC/DC conver-USB/WALL
