LM2706 - Step-Down DC-DC Converter

General Description

The LM2706 DC-DC converter is optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell.

It may also be used in many other applications.

It steps down an input voltage from 2.7V to 5.5V to a variable output from 1.5V to 3.25V up to 300 mA.

Key Features

  • n Forced and Automatic Bypass modes n Miniature 10-pin lead free micro SMD package n Only three tiny surface-mount external components required n Uses small ceramic capacitors n Low output voltage ripple ( < 10 mV typ) n Internal soft start n Current overload protection n No external compensation.

LM2706 Miniature, Variable, Step-Down DC-DC Converter with Bypass for RF Power Amplifiers PRELIMINARY February 2004 LM2706 Miniature, Variable, Step-Down DC-DC Converter with Bypass for RF Power Amplifiers General Description The LM2706 DC-DC converter is optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell. It may also be used in many other applications. It steps down an input voltage from 2.7V to 5.5V to a variable output from 1.5V to 3.25V up to 300 mA. Output voltage is set using a www.DataSheet4U.com VCON analog input for controlling power levels and efficiency of the RF PA. An internal bypass switch allows direct connection to the battery for maximum power to the RF PA. The device offers 4 modes for mobile phones and similar RF PA applications.
