LM3208 Datasheet (Texas Instruments) - Step-Down DC-DC Converter

LM3208, Step-Down DC-DC Converter

The LM3208 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell.

However, it may be used in many other applications.

It steps down an input voltage in the range from 2.7V to 5.5V to an adjustable output voltage of 0.8V to 3.6V.
