  DESIGN FEATURES L 4.5A Monolithic LED Drivers with
  3000:1 Dimming are Ideal for
  a Wide Range of High Power
  LED Applications
  by Mark W. Marosek
  Introduction The LT3478 and LT3478-1 are monolithic step-up DC/DC converters
  specifically designed to drive high
  brightness LEDs with a constant current over a wide programmable range.
  They are extremely easy to use and
  include programmable features for
  optimizing performance, reliability,
  size and overall solution cost. These
  devices can operate in boost, buckmode boost and buck-boost mode
  LED driver topologies. Depending on
  the topology, they can provide up to
  4A of LED current, a level unmatched
  by other monolithic LED drivers. The
  LT3478 and LT3478-1 are ideal for
  high power LED applications, including automotive and avionic lighting,
  and are available in a 16-pin thermally enhanced TSSOP package with
  either E-grade or I-grade temperature
  ratings.
  The LT3478 and LT3478-1 operate similarly to conventional current mode boost converters, but use LED …
