ETA3560
1A, 1.5MHz Step-Down Converter in DFN2X2-6 Package
DESCRIPTION
The ETA3560 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 ETA3560 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.
ETA3560 is housed in a tiny DFN2X2-6L package
