Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM3200 Miniature, Adjustable, Step-Down DC-DC Converter with Bypass Mode for RF Power Amplifiers November 2005 LM3200 Miniature, Adjustable, Step-Down DC-DC Converter with Bypass Mode for RF Power Amplifiers.

General Description

The LM3200 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 a variable 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.

Key Features

  • and performance for mobile phones and similar RF PA.
