ETA3406

1.5MHz 1.2A Step-Down Converter in SOT23-5 Package

DESCRIPTION

FEATURES

The ETA3406 is a high-efficiency, DC-to-DC step-down

switching regulator, capable of delivering up to 1.2A 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 ETA3406 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.

ETA3406 is housed in a tiny SOT23-5L package
