  L DESIGN IDEAS No PWM Signal Needed for Accurate
  Dim/Bright Control of Automotive
  Brake Lights and Other Signal LEDs
  Introduction by Bill Martin LEDs are quickly becoming standard
  lighting for a variety of commercial,
  automotive, and industrial applications. Some of these applications
  require wide-range brightness control,
  spurring a demand for products that
  offer PWM-based LED brightness
  control. However, many applications
  only require two settings, bright and
  dim, so generating a PWM signal for a
  binary choice is inconvenient overkill.
  The LT3592 LED driver is the solution
  to this problem. It simplifies design
  by offering two LED current settings
  with a 10:1 ratio, selected via a simple
  digital control pin. This pin has a low
  threshold voltage, but high voltage
  capability, making it very easy to
  plug into any automotive or industrial
  system. For an application such as
  automotive brake light control, the …
