LM3208 650mA Miniature, Adjustable, Step-Down DC-DC Converter for RF Power
Amplifiers
General Description
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.
Output
voltage is set by using a VCON analog input to control power levels and efficiency of the RF PA.
The LM3208 offers superior performance for mobile phones and similar RF PA applications.
