  DESIGN FEATURES L Light Up 12 LEDs from a Single-Cell
  Li-Ion Battery via Highly Integrated
  3mm Г— 2mm Dual-LED-String Driver
  by Ben Chan Introduction
  The LT3497 is a dual step-up converter capable of driving up to 12
  white LEDs from a single-cell Li-Ion
  input. The device is capable of driving
  asymmetric LED strings with independent dimming and shutdown control,
  perfect for driving backlight circuits
  in battery-powered portable devices,
  such as cellular phones, MP3 players,
  PDAs, digital cameras, and portable
  GPS devices.
  The LT3497 directly regulates
  LED current, providing consistent
  brightness for all LEDs regardless
  of variations in their forward voltage
  drop. Important features including
  internal compensation, open-LED protection, DC/PWM dimming control, a
  35V power switch and a 35V Schottky
  diode are all integrated into the part,
  making the LT3497 LED driver an
  ideal solution for space-constrained …
