Line and Load Transient Response
Available in 8-Lead SO or PDIP
Operates with Supply Voltage as Low as 2V
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.
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 200 μ A and can be
further reduced to 15 μ A in shutdown.
