USING THE EVALUATION BOARD
I
NPUT VOLTAGE RANGE
The input voltage range of these boards is
from 5.5V to 25V. The power components
have been optimized for a 12V input rail.
When running the board at an input voltage
other than 12V, use PowerArchitect
TM
5.1 to
evaluate the system performance.
I
2
C INTERFACE
The XRP7724 and XRP7725 programmable
power controllers employ a standard I
2
C
interface. Although the I
2
C signals can be
pulled up to LDO5 on board by means of
installing resistors at the locations R25 and
R26, the I
2
C bus signals are pulled up on the
controller interface board (XR77EVB-INT-1) by
default (refer to Appendix – jumpers installed
shorting pins 2 and 3 together at the locations
JP6 and JP7).
OPERATING THE EVALUATION BOARD
The XRP7724/7725EVB-DEMO-2 is designed to
be powered from either an AC/DC wall wart
(the output voltage must be in the range of
the controllers - 5.5V to 25V) connected to the
barrel connector or a test bench DC power
supply (the voltage must be in the range of
the controllers - 5.5V to 25V) connected to the
V
IN
connectors.
BRING UP PROCEDURE
Plug the XRP7724/7725EVB-DEMO-2
evaluation board and the Arduino board into
the controller interface board as shown below.
Load the
latest PowerArchitect
TM
5 software
and run it.
After selecting the proper family (Chips) and
the device (XRP7724 or XRP7725), select the
“Get Started with the EVB-DEMO2” option
when prompted as shown below.
When done, click “Create”. PowerArchitect
TM
5
will load the default configuration
automatically.
Apply Power to the board. Please refer to the
sections above on how to properly supply
power to the board and what voltage range to
use.
Turn on the Power supply.
Use USB cable to connect the computer (type
A) and the Arduino controller board (type B).
Go to the Tools tab in PA 5 and select Boards.
The software will identify communication ports
where it found the Arduino controller board.
Select the port.
