  DESIGN IDEAS Boost Converter Drives 1A White LEDs
  by Keith Szolusha
  White LEDs are brighter and more
  powerful than ever. High-power white
  LEDs, because of their extreme luminous density and ultra-compact size,
  are replacing conventional bulbs in
  flashlights, headlamps, streetlights,
  and many automotive applications—
  anywhere a conventional bulb might
  be found. Some new white LEDs,
  such as Lumileds’ Luxeon™ series,
  improve on conventional bulbs in several characteristics, including greater
  luminescence, improved response
  time, and increased durability with
  decreased size and cost.
  The challenge in using white LEDs
  in portable applications is powering
  them with the wide input voltage range
  that batteries present, such as 3.3V to
  4.2V from a lithium-ion. LEDs require
  constant current to maintain constant
  luminosity. The battery-LED DC/DC
  converter must both step up and step …
