ETA3411
The ETA3411 is a high-efficiency, DC-to-DC step-down switching regulator optimized for powering RF power amplifiers, It has a high switching frequency of 3MHz and is capable of delivering up to 2A of output current. The device operates from an input voltage range of 2.1V to 5.5V and provides and adjustable output voltages from 0.6V to VIN by tracking an external reference voltage. Therefore, the ETA3411 is ideal for powering RF PAs because power levels of PAs can be controlled by an external envelope signal and the system efficiency is optimized
ETA3411 is housed in a tiny DFN1.6x1.6- and DFN2x2-8L package
