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