Overview

5V at 600mA or 12V at 120mA from 2-Cell Supply
200µA Quiescent Current
Logic Controlled Shutdown to 15µA
Low V_CESAT Switch: 310mV at 2A Typical
Burst Mode^™ Operation at Light Load
Current Mode Operation for Excellent Line and Load Transient Response
Available in 8-Lead SO or PDIP
Operates with Supply Voltage as Low as 2V

The LT1302/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.

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.

Available in 8-pin PDIPor 8-pin SO packaging, the LT1302/LT1302-5 have the highest switch current rating of any similarly packaged switching regulators presently on the market.
