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. Up to 97% Energy Converting Efficiency Up to 3A output current at 5V output, 3.6V input Externally adjustable output voltage True Shut off during shutdown and output short- circuit protection Thermal Shutdown QFN3x3-16
