RGB LED Driver and

FeaTures
DescripTion
The LTC
®
3212 is a low noise charge pump RGB LED
driver capable of driving three LEDs up to 25mA each
from a 2.7V to 5.5V input. Low external part count (one
flying capacitor, two bypass capacitors and one to three
programming resistors) makes the LTC3212 ideally suited
for small, battery-powered applications.
Built-in soft-start circuitry prevents excessive inrush cur-
rent during start-up and mode switching. High switching
frequency enables the use of small external capacitors.
The charge pump shuts down to a high impedance mode
to prevent LED leakage while the LTC3212 is off.
Each LED may be individually turned on or off via a single
pin interface. The current through the LEDs may be indi-
vidually programmed with resistors or may share a single
programming resistor. White mode adjusts the red, green
and blue LED current ratios for a white light when all three
LEDs are programmed to be on.
LED currents are regulated using internal low dropout
current sources. Automatic mode switching optimizes
efficiency by monitoring the LED current drivers and
switches mode only when dropout is detected. The part
is available in a 3mm

2mm 12-lead DFN package.
