ETA钰泰 ETA2808E8A ESOP-8

　　在ESOP8中的42V/3A同步降压转换器钰泰升压型LED驱动电源IC

　　DESCRIPTION

　　The ETA2808 is a high-efficiency DC-to-DC step-down switching regulator that is capable of delivering up to 3A of output current. The device operates with wide input voltage range from 4.6V to 42V, making it ideal for high voltage USB charging applications.

　　The ETA2808 uses a constant current mode architecture. It includes constant current(CC)/ constant voltage(CV) output regulation and output cord compensation. It also includes external programmable switching frequency for EMI optimization and external adjustable CC current limit setting, making it a perfect solution for car charger application.

　　ETA2808 is available in ESOP8 package.
