LM3207 650mA Miniature, Adjustable, Step-Down DC-DC Converter for RF Power Amplifiers with Integrated Vref LDO
General Description
The LM3207 is a DC-DC converter optimized for powering WCDMA / CDMA RF power amplifiers (PAs) from a single Lithium-Ion cell; however they may be used in many other applications.
It steps down an input voltage from 2.
7V to 5.
5V to a variable output voltage from 0.
8V(typ.
) to 3.
6V(typ.
).
Output voltage is set using a VCON analog input for controlling power levels and efficiency of the RF PA.
The LM3207 also provides a regulated reference voltage (Vref) required by l...
