钰泰 ETA1471 FCTSOT23-6 电池充电管理芯片
科瑞芯电子-ETA1471FT2G-18V/3A高效同步降压变换器
ETA1471 is a wide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. With a fixed switching frequency of 500KHZ, this current mode PWM controlled converter allows the use of small external components. such as ceramic input and output caps, as well as small inductors. ETA1471 also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. The IC can stand off input voltage as high as 25V, making it an ideal solution for industrial applications such as LCD TV, Set Top Box, Portable TV.etc
