ETA1090
1MHz High Output current High Efficiency Synchronous Step-Up Converter
DESCRIPTION
FEATURES
ETA1090 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 91% 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. ETA1090 also incorporates ETA
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

overload and short-circuit conditions. All of these features are
integrated in a tiny DFN3x3-12 package. With 1MHz switching
frequency, small external input and output capacitors and
inductor can be used.
