ETA1089
5V/2.5A Output, 1MHz Synchronous Step-Up Converter with DCP emulator
DESCRIPTION
FEATURES
ETA1089 is an ETA Solutions’ high efficiency, high frequency
synchronous Step-Up converter, capable of delivering output
current up to 2.5A at a 5V output from input as low as 3.3V.
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. ETA1089 also integrates an
USB emulator that provides correct electrical signature on the
D+/D- for charging compliant devices. ETA1089 also
Up to 97% Energy Converting Efficiency
Up to 2.5A output current at 5V output, 3.3V input
Dedicated Charging Port (DCP) emulator
True Shut off during shutdown and output short-
circuit protection
Thermal Shutdown
DFN3x3-12
APPLICATIONS
Power Bank
Mobile 3G/4G WLAN
Mobile Bluetooth music player and speaker
R
incorporates ETA Solutions’ True-Shutoff○ technology that
protects against 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.
