ETA1469
ETA1469 is COT Synchronous Step-Down Converter manufactured by ETA.
18V, 2A, COT Synchronous Step-Down Converter in SOT23-6
DESCRIPTION
Features
ETA1469 is a wide input range, high-efficiency and highfrequency 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. The adaptive COT control also maintains a constant switching frequency across line and load. An OVP function protects the IC itself and its downstream system against input voltage surges. With this OVP function, the IC can stand off input voltage as high as 28V, making it an ideal solution for industrial applications such as LCD TV, Set Top Box, IP CAM, etc.
ETA1469 is available in SOT23-6 package.
