ETA3409

The ETA3409 is a high-efficiency, DC-to-DC step-down switching regulator. capable of delivering up to 3A of output current. The devices operate from an input voltage range of 2.4V to 7.3V and provide output voltages from 0.6V to VIN, making theETA3409 ideal for low voltage power conversions. Running at a fixed frequency of 1MHz 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. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improves design reliability.
