Launching the GUI
1.
Ensure that the evaluation board, the auxiliary power
board, and the daughter card are already plugged into
the main power board. If they are mishandled during
shipment, ensure that they are properly attached as per
Figure 1.
2.
Ensure that the CTRL switch or hardware PSON (SW2) is
turned to the Off position (switch position on the right).
3.
Plug one end of the USB to I
2
C adapter in Jumper J6 or in
the connector on the daughter card, and plug the other end
in the USB port of the PC.
4.
Launch the
ADP1055
GUI. The software GUI should
report that the
ADP1055
has been located with the
address. Click
Finish
to proceed.

The
ADP1055
in the evaluation kit is preprogrammed with
the board and command settings, so this step is optional.
If you want to load the default command and board
settings file from a local folder, click the
Load Command
and Board settings from a ‘.55s’ file to ADP1055
icon.

POWERING UP
1.
Connect a dc source (voltage range of 38 V dc to 60 V dc)
at the input terminals and an electronic load at the output
terminals. Refer to Figure 6 for the correct configuration.
2.
Connect voltmeters on the input terminals and output
terminals separately as shown in Figure 6.
3.
Connect the voltage probes at different test pins. Ensure
that the differential probes are used and that the ground of
the probes are isolated if the measurements are made on
the primary and secondary side of the transformer
simultaneously.
4.
Set the electronic load to 5 A.
5.
Turn the CTRL switch (SW2) to the On position.
The evaluation board should now be up and running, and ready
for evaluation. The output should now read 12 V dc.
After successful startup when the PSU is in steady state
condition, LEDs provide the status of the board.
