DESCRIPTIO  
FEATURES  
■
High Efficiency: 90% Typical Over Entire  
The LTC®3453 is a synchronous buck-boost DC/DC con-  
verter optimized for driving up to 4 white LEDs at a  
combined current of up to 500mA from a single Li-Ion  
battery input. The regulator operates in either synchro-  
nous buck, synchronous boost, or buck-boost mode,  
depending on input voltage and LED maximum forward  
voltage. Optimum efficiency is achieved using a propri-  
etary architecture that determines which LED requires the  
largest forward voltage drop at its programmed current,  
and regulates the common output rail for lowest dropout.  
Efficiency of 90% can be achieved over the entire usable  
range of a Li-Ion battery (2.7V to 4.2V).

APPLICATIO S  
■
Cell Phones  
■
Digital Cameras  
A high constant operating frequency of 1MHz allows the  
use of a small external inductor. The LTC3453 is offered  
in a low profile (0.75mm) thermally enhanced 16-lead  
(4mm x 4mm) QFN package.
