LM3674 2MHz, 600mA Step-Down DC-DC Converter in SOT 23-5
General Description
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
voltage versions.
The device offers superior 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 d...
