  DESIGN IDEAS Triple Output TFT-LCD Bias Supply
  Uses All Ceramic Capacitors by Gary Shockey
  Current power supply requirements for TFT-LCD panels call for an
  8V or 10V main supply plus two or
  more auxiliary outputs. The overall
  layout must be small and meet tight
  height requirements of under 2mm.
  Bulky inductors and capacitors must
  be eliminated if the design is to meet
  space requirements. The circuit described in this design idea features
  the new LT1949 and delivers 8V at
  200mA from 3.3V while generating
  auxiliary 24V and –8V outputs capable
  of 10mA of output current.
  The LT1949 is a boost switching
  regulator that comes in the MSOP-8
  package and has an integrated 1.1A
  NPN power transistor. For this appliD1 VOUT
