ETA3409>>>3MHz 2AHigh ŋ Step-Down Converter
ETA3409=LA8103=SY8089
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 0.6V
to VIN, making the ETA3409 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 thermaloverload
protection improves design reliability.
ETA3409 is housed in a tiny SOT23-5L package
