General Description

The ETA3458 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 2.5V to 5.5V and provide output voltages from 0.6V to VIN, making the ETA3458 ideal for low voltage power conversions.

ETA3458 adopts an Adaptive COT control scheme that enables very fast transient response and provides a very smooth transition when the output varies from light load to heavy load.
