DESCRIPTIO  
FEATURES  
The LT®1615/LT1615-1 are micropower step-up DC/DC  
converters in a 5-lead SOT-23 package. 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. Both devices feature a  
quiescent current of only 20µA at no load, which further  
reduces to 0.5µA in shutdown. A current limited, fixed off-  
time control scheme conserves operating current, result-  
ing 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 LT1615s low off-time of  
400ns permits the use of tiny, low profile inductors and  
capacitors to minimize footprint and cost in space-con-  
scious portable applications.
