  L DESIGN FEATURES ±32V Triple-Output Supply for LCDs,
  CCDs and LEDs Includes Fault
  Protection in a 3mm Г— 3mm QFN
  by Eko T. Lisuwandi Introduction
  The task of designing a battery powered system with multiple high voltage
  supplies is a daunting one. In such
  systems board space is at a premium
  and high efficiency is required to
  extend battery life. Supplies must be
  sequenced in start-up and shut-down,
  and multiple supplies must be able to
  maintain regulation without interaction across supplies.
  The LT3587 is a 1-chip solution
  that combines three switching regulators and three internal high voltage
  switches to produce two high voltage
  boost converters and a single high voltage inverter. The LT3587 is designed to
  run from inputs ranging from 2.5V to
  6V, making it ideal for battery powered
  systems. Small package size and low component count produces a small,
  efficient solution. Typical applications
  include digital still and video cameras,
  high performance portable scanners
  and display systems, PDAs, cellular …

  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 …
