LM3370 - Dual Synchronous Step-Down DC-DC Converter

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 600 mA load per channel.

Key Features

  • The LM3370 offers superior features and performance for portable systems with complex power management requirements. Automatic intelligent switching between PWM lownoise and PFM low-current mode offers improved system efficiency. Internal synchronous rectification enhances the converter efficiency without the use of further external devices. There is a power-on-reset function that monitors the level of the output voltage to avoid unexpected power losses. The independent enable pin for each outp.
