钰泰 ETA1466 SOT23-6 电池充电管理芯片

　　DESCRIPTION

　　EIA1466isa wide input range, hingifiency and high frequency DC-

　　to-DC step-down swithing regulator, capable of delivering up to2A 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,

　　EIA1466goes into aPFMmode that saves sithingloss ahievinghigh

　　efcienc. The adaptive COT control also maintains aconstant switching

　　frequency aCrosS line and load. An 0VP 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 25V, making itan

　　ideal solution for indutrial aplications such as LCD TV, Set Top Box,

　　Portable TV, etc.

　　ETA1466 is ailable in SOT23-6 package.
