LTC3675  
7-Channel Configurable  
High Power PMIC  
FEATURES  
DESCRIPTION  
n
Four Monolithic Synchronous Buck DC/DCs  
The LTC®3675 is a digitally programmable high efficiency  
multioutput power supply plus dual string LED driver IC  
optimizedforhighpowersinglecellLi-Ion/Polymerapplica-  
tions. The DC/DCs consist of four synchronous buck con-  
verters (1A/1A/500mA/500mA), one synchronous boost  
DC/DC (1A), and one buck-boost DC/DC (1A) all powered  
from a 2.7V to 5.5V input. The 40V LED driver can regulate  
up to 25mA of current through two LED strings with up to  
10 LEDs each. The LED driver may also be configured as  
a general purpose high voltage boost converter.  
(1A/1A/500mA/500mA)

Applications  
Pushbutton ON/OFF/RESET control and a power-on reset  
output provide flexible and reliable power-up sequenc-  
ing. The LTC3675 is available in a low profile (0.75mm),  
thermally enhanced 44-lead 4mm × 7mm QFN package.
