ETA1092

 

 

1MHz High Output current High Efficiency Synchronous Step-Up Converter

 

FEATURES

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

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.
