  DESIGN IDEAS L Entire RGB LED Driver Fits in Miniscule
  by Zachary Lewko
  3mm Г— 2mm Package
  Introduction
  The LTC3212 charge pump RGB LED
  driver is an ideal solution for highly
  space-constrained portable devices
  such as cellular phones, PDAs, digital cameras and media players. The
  LTC3212 features an internal low
  noise charge pump utilizing a single
  external flying capacitor. This charge
  pump operates in 1Г— mode until one
  of the LEDs drops out of regulation,
  after which it switches to 2Г— mode,
  automatically maintaining proper LED
  current while reducing power loss
  and minimizing switching noise. The
  LTC3212 is designed with flexibility in
  mind and can be used for driving RGB
  backlights, keypad back lighting, or a
  general purpose LED such as a multicolor status indication LED. Battery/Supply Voltage
  The LTC3212 is designed to operate
  from 2.7V to 5.5V inputs, making it an …
