钰泰 ETA1092Q3Q 高输出电流同步升压转换器

　　DESCRIPTION

　　ETA1092 is an ETA Solutions' high efficiency. high frequency synchronous Step-Up converter, capable of delivering output current up to 3A at a 5V output from a 3.6V input.With a low Rdson Power MOS and a built-in synchronous rectifier. its efficiency can be as high as 93% at a 5V/2.1A load.This greatly minimizes power dissipation and reduces heat on the IC. making it ideal for applications that require small board space and have stringent temperature constraints. such as power banks and mobile devices. ETA1092 also incorporates ETA Solutions' True-Shutoff®technology that protects against overload and short-circuit conditions. All of these features are integrated in a tiny QFN3x3-16 package. With 1MHz switching frequency, small external input and output capacitors and inductor can be used.
