描述

The ETA3409 is a high-efficiency, DC-to-DC step-down
switching regulator, capable of delivering up to 1.5A/2A of
output current. The devices operate from an input voltage
range of 2.6V to 5.5V and provide output voltages from Q.6
to VIN, making the ETA3409 ideal for low voltage pow er
conversions. Running ata fixed frequency of 3MHz alloWs theiny
use of small inductance value and low DCR inductors,
thereby achieving higher efficiencies. Other external
components. such as ceramic input and output caps. can
also be small due to higher switching frequency, while
maintaining exceptional low noise output voltages. Built-in
EMI reduction circuitry makes this converter ideal power
supply for RF applications. Internal soft-start control
circuitry reduces inrush current. Short-circuitand thermal
overload protection improves design reliability.
ETA3409 is housed in a tiny SOT23-5L package
