Part Number: LM3262
Function: 6MHz, 800mA Miniature, Adjustable, Step-Down DC-DC Converter
Package: 9DSBGA Type
Manufacturer: Texas Instruments
Pinouts: 
Description
The LM3262 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 such as USB-powered portable applications.
The device’s 2.5V to 5.5V input voltage can be stepped down to an adjustable output voltage range from 0.4V to 3.6V. Output voltage is set using a VCON analog input which enables improved RF stage PA efficiencies.
