The LT1316IS8#PBF is a micropower step-up DC-to-DC Converter with programmable peak current limit. It 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 30 and 500mA by adjusting one resistor. This is particularly useful for DC/DC converter operating from high source impedance inputs such as lithium coin cells or telephone lines. The fixed OFF-time, variable on-time regulation scheme results in quiescent current of only 33µA in active mode. Quiescent current decreases to 3µA in shutdown with the low-battery detector still active.
