ETA1088
5V/2A Output, 1MHz Synchronous Step-Up Converter with DCP emulator
DESCRIPTION
FEATURES
ETA1088 is an ETA Solutions’ high efficiency, high frequency
synchronous Step-Up converter, capable of delivering output
current up to 2A 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 90% at a 5V/2A 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. ETA1088 also integrates an
USB emulator that provides correct electrical signature on the
D+/D- for charging compliant devices. ETA1088 also
