  100V Controller Drives High Power LED Strings from Just about
  Any Input – Design Note 461
  by Keith Szolusha
  Introduction
  Strings of high power solid-state LEDs are replacing
  traditional lighting technologies in large area and high
  lumens light sources because of their high quality light
  output, unmatched durability, relatively low lifetime cost,
  constant-color dimming and energy efficiency. The list of
  applications grows daily, including LCD backlights and
  projection, industrial and architectural lighting, automotive lights, streetlights, billboards and stadium lights.
  As the list expands, so does the range of VIN for the LED
  drivers. LED drivers must be able to handle wide ranging
  inputs, including transient voltages of automotive batteries, a wide range of other batteries and wall wart voltages.
  For LED lighting manufacturers, applying a different LED
  driver for each application means stocking, testing and
  designing with a number of controllers. It would be better
  to use just one that can be applied to many solutions.
  The LT3756 high voltage LED driver features a unique
  topological versatility that allows it to be used in boost,
  buck-boost mode, buck mode, SEPIC, flyback and other
  topologies. Its high power capability provides potentially
  hundreds of watts of LED power over a wide input voltage range. Its 100V floating LED current sense inputs provide …

  or MSE Drives High Power LED Strings
  from Just About Any Input by Keith Szolusha
  Introduction
  Strings of high power solid-state
  LEDs are replacing traditional lighting
  technologies in large area and high
  lumens light sources because of their
  high quality light output, unmatched
  durability, relatively low lifetime cost,
  constant-color dimming and energy efficiency. The list of applications grows
  daily, including LCD television backlights and projection system bulbs,
  industrial and architectural lighting
  systems, automotive headlamps, taillights and indicator lights, computer
  monitors, street lights, billboards and
  even stadium lights.
  As the number of applications expands, so does the complexity of input
  requirements for the LED drivers.
  LED drivers must be able to handle
  wide ranging inputs, including the
  harsh transient voltage environment
  presented by automotive batteries,
  the wide voltage range of the Li-ion …

  L DESIGN IDEAS Don’t Want to Hear It? Avoid the
  Audio Band with PWM LED Dimming
  at Frequencies Above 20kHz by Eric Young
  Introduction
  The requirements of LED drivers become more demanding as application
  designers exploit the unique characteristics of LEDs. Linear Technology offers
  a complete portfolio of LED drivers
  with the performance levels required to
  meet even the most challenging design
  requirements. One area where these
  LED drivers especially excel is in the
  performance and flexibility of their
  PWM dimming capabilities. LEDs can
  be turned on and off rapidly—it takes
  only nanoseconds to illuminate or
  extinguish the source. PWM dimming
  exploits this characteristic to achieve
  orders of magnitude dimming, even
  while maintaining a constant output
  spectrum over the entire dynamic light
  intensity range.
  The broad field of available LED
  drivers narrows quite a bit when …
