.. LM3208 650mA Miniature, Adjustable, Step-Down DC-DC Converter for RF Power Amplifiers April 2006 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....
