3MHz 2A High ŋ Step-Down Converter in DFN2x2-8L Package

DESCRIPTION

The ETA3410 is a high-efficiency, DC-to-DC step-down

switching regulator, capable of delivering up to 2A 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 ETA3410 ideal for low voltage power

conversions. Running at a fixed frequency of 3MHz 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.

ETA3410 is housed in a tiny DFN2x2-8L package
