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

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.
