LM3673 Overview
The LM3673 step-down DC-DC converter is optimized for powering low voltage circuits from a single Li-Ion cell battery and input voltage rails from 2.7V to 5.5V. It provides up to 350mA load current, over the entire input voltage range. There are several different fixed voltage output options available as well as an adjustable output voltage version ranging from 1.1V to 3.3V.
