General Description

ETA1477 is a wide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 2A of output current.

It 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.

During light load, ETA1477 goes into a PFM mode that saves switching loss achieving high efficiency.

Key Features
