ACE712E
5V/2A Output, 1MHz Synchronous Step-Up Converter with DCP emulator
Description
ACE712E is an ACE 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. ACE712E also integrates an USB emulator that provides correct electrical signature on the
D+/D- for charging compliant devices. ACE712E also incorporates ACE Solutions True-Shutoff ^○R
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.
