  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
