RGB LED Driver and  
Charge Pump  
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  
programmingresistors)makestheLTC3212ideallysuited  
for small, battery-powered applications.

■
Single Wire Enable Control for All LEDs  
■
White Mode Adjusts R, G, B Currents for White Light  
■
25mA Maximum LED Current  
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.

■
Available in 12-Lead (3mm × 2mm) DFN Package  
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.
