Product details

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.

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.
