DESCRIPTIO  
FEATURES  
The LT®1615/LT1615-1 are micropower step-up DC/DC  
converters in a 5-lead low profile (1mm) ThinSOT pack-  
age. The LT1615 is designed for higher power systems  
with a 350mA current limit and an input voltage range of  
1.2V to 15V, whereas the LT1615-1 is intended for lower  
power and single-cell applications with a 100mA current  
limit and an extended input voltage range of 1V to 15V.  
Otherwise, the two devices are functionally equivalent.  
Bothdevicesfeatureaquiescentcurrentofonly20µAatno  
load, which further reduces to 0.5µA in shutdown. A  
current limited, fixed off-time control scheme conserves  
operating current, resulting in high efficiency over a broad  
range of load current. The 36V switch allows high voltage  
outputs up to 34V to be easily generated in a simple boost  
topology without the use of costly transformers. The  
LT1615’slowoff-timeof400nspermitstheuseoftiny,low  
profile inductors and capacitors to minimize footprint and  
cost in space-conscious portable applications.
