The LT ? 1073 is a versatile micropower DC/DC converter.
The device requires only three external components to
deliver a fixed output of 5V or 12V. The very low minimum
supply voltage of 1V allows the use of the LT1073 in
applications where the primary power source is a single
cell. An on-chip auxiliary gain block can function as a low-
battery detector or linear post-regulator.
Average current drain of the LT1073-5 used as shown in
the Typical Application circuit below is just 135 μ A un-
loaded, making it ideal for applications where long battery
life is important. The circuit shown can deliver 5V at 40mA

from an input as low as 1.25V and 5V at 10mA from a 1V
input.

The device can easily be configured as a step-up or step-
down converter, although for most step-down applica-
tions or input sources greater than 3V, the LT1173 is
recommended. Switch current limiting is user-adjustable
by adding a single external resistor. Unique reverse-
battery protection circuitry limits reverse current to safe,
nondestructive levels at reverse supply voltages up to
1.6V.
