LM3674 Datasheet (National Semiconductor) - 600mA Step-Down DC-DC Converter

LM3674, 600mA Step-Down DC-DC Converter

The LM3674 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 600mA load current, over the entire input voltage range.

There are several fixed output voltages and adjustable output vo

LM3674 Features

* and performance for mobile phones and similar portable systems. During PWM mode, the device operates at a fixed-frequency of 2 MHz (typ). Internal synchronous rectification provides high efficiency during PWM mode operation. In shutdown mode, the device turns off and reduces battery consumption to 0
