钰泰 ETA1467 SOT23-6 电池充电管理芯片

　　DESCRIPTION

　　ETA1467 is a wide input range, high- ecienc and high frequency DC-

　　t0-DC step-down switching regulator, capable of delivering up to3Aof

　　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,

　　ETA1467 goes into aPFMmode that saves switchingloss achievinghigh

　　eficiency. The adaptive COT control also maintains a constant switching

　　frequency across line and load.An OVP function protects the |C 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 it an

　　ideal solution for industrial applications such as LCDTV, Set Top Box,

　　PortableTV, etc.

　　ETA1467 is available in S0T23-6 package.
