  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
