  DESIGN IDEAS Simple Converter Drives Luxeon
  White LEDs from Batteries by Michael Nootbaar
  Introduction current drive. Existing boost circuits
  generally use voltage feedback switching converters with extra circuitry to The high output 1W white LEDs from
  Luxeon and Nichia provide illumination levels close to 12W incandescent
  levels while dissipating only 1W and
  lasting for 50,000 hours or more. These
  devices promise enormous power savings and reduced maintenance cost
  for many lamp applications. However,
  these LEDs must be driven with a
  constant current to maintain proper
  brightness. The forward voltage drop
  varies between 2.8V and 4.0V over
  process and temperature extremes.
  The circuit used to drive the LED must
  compensate for this forward voltage
  variation while maintaining constant The LTC3490 provides a
  simple solution for boosting
  a single or dual cell battery
  voltage to the necessary
  LED forward voltage and
  regulating the current
  through the LED load. …
