General Description

The FAN5909 is a high−efficiency, low−noise, synchronous, www.onsemi.com step−down, DC−DC converter optimized for powering Radio Frequency (RF) Power Amplifiers (PAs) in handsets and other mobile applications.

Load currents up to 2.5 A are allowed, which enables GSM / EDGE, 3 G/3.5 G, and 4G platforms under very poor VSWR conditions.

1 The output voltage may be dynamically adjusted from 0.40 V to 3.60 V, proportional to an analog input voltage VCON ranging from 0.16 V to 1.44 V, optimizing power−added efficiency.

Overview

FAN5909 Multi-Mode Buck Converter with LDO Assist for GSM / EDGE, 3 G/3.

Key Features

Solution Size < 9.52 mm2 Operation at Low Power and Low Output Voltage for Maximum Low Current Efficiency.
2.7 V to 5.5 V Input Voltage Range.
