■ The LT®1316 is a micropower step-up DC/DC converter
that operates from an input voltage as low as 1.5V. A
programmable input current limiting function allows precise control of peak switch current. Peak switch current
can be set to any value between 30mA and 500mA by
adjusting one resistor. This is particularly useful for
DC/DC converters operating from high source impedance
inputs such as lithium coin cells or telephone lines. Precise Control of Peak Switch Current
Quiescent Current:
33µA in Active Mode
3µA in Shutdown Mode
Low-Battery Detector Active in Shutdown
Low Switch VCESAT: 300mV at 500mA …
