  L DESIGN IDEAS Complete Power Solution for Digital
  Cameras and Other Complex
  Compact Portable Applications
  by Brian Shaffer Introduction
  Digital cameras, portable GPS systems,
  MP3 players and other feature-rich
  mobile devices have complicated
  power requirements. In these complex
  devices, the flow of power must be
  carefully managed between a number of specialized sources and loads,
  including charging/discharging the
  battery, current-limited USB power
  and a set of multivoltage power supply rails, including negative rails for
  CCDs or LCDs. The supply rails must
  be sequenced and tracked and faults
  must be handled cleanly and communicated to a microcontroller.
  When these requirements are
  added together, the task of squeezing
  an efficient and robust power system
  into a handheld device can seem near
  impossible. Linear Technology solves
  this problem with a family of devices
  called PMICs (Power Management Integrated Circuits) that greatly simplify …

  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
