ETA3408

1A, 1.5MHz Step-Down Converter in SOT23-5 Package

DESCRIPTION

FEATURES

The ETA3408 is a high-efficiency, DC-to-DC step-down

switching regulator, capable of delivering up to 1A of output

current. The devices operate from an input voltage range

of 2.6V to 5.5V and provide output voltages from 0.6V to

VIN, making the ETA3408 ideal for low voltage power

conversions. Running at a fixed frequency of 1.5MHz allows

the 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-circuit and

thermal-overload protection improves design reliability.

ETA3408 is housed in a tiny SOT23-5L package
