  L DESIGN FEATURES High Current/High Speed LED Driver
  Revolutionizes PWM Dimming
  by Josh Caldwell Introduction
  Power drivers that can produce regulated high current pulses are used
  in a number of lighting applications,
  ranging from high current LEDs in
  DLP projectors to high power laser
  diodes. For instance, in high end
  video projectors, high power LEDs are
  used to produce color illumination.
  The RGB LEDs in these projectors
  require precise dimming control for
  accurate color mixing—in this case,
  more control than simple PWM dimming can offer. Typically, to achieve
  the wide dynamic range required in
  color mixing, LED drivers must be
  able to rapidly switch between the
  two disparate regulated peak current
  states, and overlay PWM dimming
  without disruption. The LT3743 has
  the ability to meet these demanding
  accuracy and speed requirements.
  The LT3743 is a synchronous …
