ACE725E
24V , 1.2A High Efficiency Step-Down Converter
Description
The ACE725E is a wide input range, high-efficiency, high frequency DC-to-DC step-down switching
regulator, capable of delivering up to 1.2A of output current. With a fixed switching frequency of 1.4MHz,
this current mode PWM controlled converter allows the use of small external components, such as
ceramic input and output caps, as well as small inductors, while still providing low output ripples. Together
with the tiny package ACE725E is in, without external compensation components, it is an ideal solution for
system designer with stringent board space requirements. ACE725E also employs a proprietary control
scheme that switches the device into a power save mode during light load, thereby extending the range of
high efficiency operation.
ACE725E is available SOT23-6 Packages.
