General Description

The LM3204 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell.

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

The output voltage is set using an analog input ( VCON) for optimizing efficiency of the RF PA at various power levels.
