LT3486  
Dual 1.3A White LED  
Step-Up Converters with  
Wide Dimming  
FEATURES  
DESCRIPTION  
The LT®3486 is a dual step-up DC/DC converter  
specifically designed to drive up to 16 White LEDs (8 in  
series per converter) at constant current from a single  
Li-Ion cell. Series connection of the LEDs provides identi-  
cal LED currents resulting in uniform brightness. The two  
independentconvertersarecapableofdrivingasymmetric  
LED strings.

Independent Dimming and Shutdown Control of the  
LED Drivers  
n
Drives Up to 16 White LEDs at 25mA (8 per Driver)  
from a Single Li-Ion Cell  
n
Drives Up to 16 White LEDs at 100mA (8 per Driver)  
from 12V Supply  
The dimming of the two LED strings can be controlled  
independently via the respective CTRL pins. An internal  
dimmingsystemallowsthedimmingrangetobeextended  
up to 1000:1 by feeding a PWM signal to the respective  
PWMpins.TheLT3486operatingfrequencycanbesetwith  
an external resistor over a 200kHz to 2.5MHz range. A low  
200mVfeedbackvoltage( 3ꢀaccuracy)minimizespower  
loss in the current setting resistor for better efficiency.  
Additional features include output voltage limiting when  
LEDs are disconnected and overtemperature protection.
