  DESIGN IDEAS Simple and Efficient Way to Provide
  Three Supply Voltages for
  Small TFT LCDs
  by Bryan Legates
  TFT LCDs used in portable devices
  today typically need three different
  supply voltages: 5V, 15V, and –10V.
  One way to generate these three voltages is to use a single DC/DC
  converter and a large number of external components, but this results
  in mediocre line and load regulation.
  The LT1944-1 dual micropower DC/
  DC converter simplifies LCD power
  supply design by generating three
  well-regulated output voltages using
  a small number of external components. Both DC/DC converters in the
  DESIGN IDEAS

  Small TFT LCDs .27 LT1944-1 use a constant-off-time
  Burst ModeВ® control scheme to ensure high efficiency at very light load
  currents. The two converters are independently optimized for high and
  low step-up ratios: the first converter
  generates –10V and 15V using a …
