FEATURES  
DESCRIPTION  
The LM2703 is a micropower step-up DC/DC in a  
small 5-lead SOT-23 package. A current limited, fixed  
off-time control scheme conserves operating current  
resulting in high efficiency over a wide range of load  
conditions. The 22V switch allows for output voltages  
as high as 21V. The low 400ns off-time permits the  
use of tiny, low profile inductors and capacitors to  
minimize footprint and cost in space-conscious  
portable applications. The LM2703 is ideal for LCD  
panels requiring low current and high efficiency as  
well as white LED applications for cellular phone  
back-lighting. The LM2703 can drive up to 4 white  
LEDs from a single Li-Ion battery.
