  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 …
