SNVS405G – DECEMBER 2005 – REVISED APRIL 2015 LM3674 2-MHz, 600-mA Step-Down DC-DC Converter in SOT-23
1 Features 3 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
2.7 V to 5.5 V. It provides up to 600-mA load current
over the entire input voltage range. There are several
fixed output voltages and adjustable output voltage
versions. 1 Input Voltage Range From 2.7 V to 5.5 V
