ETA3427
ETA3427 is 1.2A Output Synchronous BUCK manufactured by ETA.
DESCRIPTION
The ETA3427 is a high-efficiency, DC-to-DC stepdown switching regulator, capable of delivering up to 1.2A of output current. It has an ultra-low quiescent current 2u A when there is no load. Running at a fixed frequency of 1.4MHz allows the use of small inductance value and low DCR inductors, thereby achieving higher efficiencies. Other external ponents, such as ceramic input and output caps, can also be small due to higher switching frequency, while maintaining exceptional low noise output voltages. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improves design reliability.
ETA3427 is housed in a tiny SOT23-5 and DFN2x2-6 package.
