AAT1171 datasheet

Description :

The AAT1171 SwitchReg dynamically controls the operating voltage of a WCDMA or CDMA power amplifier inside single-cell, 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.

• VIN Range: 2.7V to 5.5V
• Variable Output Voltage: 0.6V to 3.6V
• 600mA Output Current
• DAC Input: 0.2V to 1.2V
• High Output Accuracy: ±3%
• 45µA No Load Quiescent Current
