Powering Minds of the Smart

3MHz, Output Adjustable, 2A Synchronous Buck Converter for RF Power Amplifiers

DESCRIPTION

FEATURES

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 2.4V 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 DFN2x2-8L package
