ETA3415
1A, 3MHz Step-Down Converter in SOT563 Package
DESCRIPTION
FEATURES
The ETA3415 is a high-efficiency, DC to DC step-down Up to 96% Efficiency
switching regulator, capable of delivering up to 1A of Up to 1A Max Output Current
output current. The devices operate from an input 3MHz Switching Frequency
voltage range of 2.6V to 7V and provide output voltages Light Load operation
from 0.6V to VIN, making the ETA3415 ideal for low Internal Compensation
voltage power conversions. Running at a fixed SOT563 Package
frequency of 3MHz allows the use of small inductance DFN1.6x1.6-6 Package
value and low DCR inductors, thereby achieving higher RoHS Compliant
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
APPLICATIONS
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.
