  L DESIGN IDEAS 5-Output High Current Power
  Supply for TFT-LCDs in a Low Profile
  QFN Features Space-Saving 2MHz
  Switching Regulators
  by Kevin Huang
  Introduction
  The LT3513 is a highly integrated,
  5-output regulator designed to provide all the supply voltages typically
  required by large TFT liquid crystal
  displays (LCDs) with a single IC. The
  part features a step-down switching
  regulator to produce a 3.3V or 5V
  logic voltage from a wide voltage range
  input, such as automotive battery.
  A lower voltage logic supply can be
  generated from the first supply by
  adding an external NPN driven by an
  internal linear regulator. The other
  three on-chip regulators provide the
  three bias voltages required by LCDs: a
  high power boost regulator to generate
  AVDD, a low power boost regulator to
  generate VON and an inverting regulator to provide VOFF. …
