The LT ®1308 is a micropower, fixed frequency boost DC/DC converter that operates from an input voltage as low as 1V. Capable of delivering 5V at load current of 1A from a single Li-Ion cell, the LT1308 also features power saving Burst Mode operation at light loads. High efficiency is maintained over a broad 1mA to 1A load range.
