F
The LT®1302/LT1302-5 are micropower step-up DC/DC  
converters that maintain high efficiency over a wide  
range of output current. They operate from a supply  
voltage as low as 2V and feature automatic shifting  
between Burst Mode operation at light load, and current  
mode operation at heavy load.

Burst ModeTM Operation at Light Load  
Current Mode Operation for Excellent  
Line and Load Transient Response  
Available in 8-Lead SO or PDIP  
The internal low loss NPN power switch can handle  
current in excess of 2A and switch at frequencies up to  
400kHz. Quiescent current is just 200µA and can be  
further reduced to 15µA in shutdown.
