DESIGN IDEASвЂ‰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 …
