LM3673 Features

* and performance for mobile phones and similar portable systems. The LM3673 uses intelligent automatic switching between PWM and PFM for better efficiency. During PWM mode, the device operates at a fixed-frequency of 2 MHz (typ). Hysteretic PFM mode extends the battery life by reducing the quiescent

LM3673 General Description

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 availab.
