ETA1661 Overview
FEATURES ETA1661 is a wide input range, high efficiency and high frequency DC to DC step-down switching regulator, capable of delivering up to 4A 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, ETA1661 goes into a PFM mode that saves switching loss...
