General Description

The LM3370 is a dual step-down DC-DC converter optimized for powering ultra-low voltage circuits from a single Li-Ion battery and input rail ranging from 2.7V to 5.5V.

It provides two outputs with 600mA load per channel.

The output voltage range varies from 1V to 3.3V and can be dynamically controlled using the I2Ccompatible interface.
