  DESIGN FEATURES Triple Output LCD Power Supply
  Delivers 95% Efficiency from a
  Tiny 3mm x 3mm Package by John Bazinet
  Introduction
  Today’s handheld products pack more
  functionality in less space while demanding improved battery life over
  products of the previous generations.
  The only way to achieve both is to improve power efficiency in the device
  wherever possible. The color LCD display system is a good place to start,
  since it is an increasingly popular, but
  power hungry feature. The LTC3450
  improves battery life and saves space
  by delivering a 95% efficient color LCD
  bias solution in a low profile (0.8mm
  tall), 3mm Г— 3mm package.
  Figure 1 shows a block diagram of
  the LTC3450—a complete triple output
  LCD power converter—in a low noise
  5.1V, 10mA output synchronous step
  up DC/DC converter. The charge pump based voltage tripler develops a 15V
  output and a voltage inverter develops
  –10V. The 15V and –10V outputs are
  used in the LCD display for VGL and …
