General Description

The AAT1171 SwitchReg, a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family, has been specifically designed to dynamically control the operating voltage of a WCDMA or CDMA power amplifier inside single lithium-ion battery-powered systems.

The AAT1171 outputs a voltage between 0.6V and 3.6V, thereby optimizing the amplifier efficiency at both low and high transmit levels.

AAT1171

Overview

600mA Voltage-Scaling Step-Down Converter for RF Power Amplifiers with Bypass Switch.

Key Features

  • SwitchReg™ The AAT1171 output voltage is controlled via an.
  • analog signal from the baseband processor. It can.
  • deliver 600mA of continuous load current while.
  • maintaining a low 45µA of no load quiescent current.
  • The 2MHz switching frequency minimizes the size of.
  • external components while keeping switching losses.
  • low. A low resistance MOSFET, typically 230mΩ,.
