LM3677 Overview
The LM3677 step-down DC-DC converter is optimized for powering ultra-low voltage circuits from a single Li-Ion cell battery and input voltage rails from 2.7V to 5.5V. It provides up to 600 mA load current over the entire input voltage range. The LM3677 is configured to different fixed voltage output options as well as an adjustable output voltage version range from 1.2V to 3.3V.
