Product Summary
The LT1316CMS8#TR 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. Applications are (1)Battery Backup; (2)LCD Bias; (3)Low Power – 48V to 5V/3.3V Converters.
