QUICK START GUIDE
1.
Download the hot swap and power monitor software from
user guide
for more information).
2.
Connect the mini evaluation board (
to the isolation board (
) using the
8-way connector and a Micro-MaTch ribbon cable.
3.
Connect the isolation board (
) to a PC
through the 10-way connector and the
dongle. The blue LED, labeled ISO, on the isolation board
illuminates.
4.
Connect the power supply to the mini evaluation board
(
) using thick wires.
5.
To confirm that the boards are configured correctly, set the
output of the power supply to 48 V with less than a 1 A
current limit and with no load capacitance. If the boards
are configured correctly, the green LEDs, labeled
D_PWRGD on the
on the
, illuminate.
6.
Press the RESTART push-button on the mini evaluation
board (
). The green LEDs, labeled
D_PWRGD and PWRGD, both turn off, and then turn
back on after 10 sec.
7.
You can use the SHDN2 switch and SHDN push-button on
the isolation board (
) to turn off
the hot swap.
8.
If a latch event occurs (for example, a short circuit during
operation), the red LED, labeled LATCH, illuminates on
the isolation board (
). The latch
event can be cleared with a CLEAR FAULT PMBus command
or by pressing the DELATCH push-button.
9.
Disable the hot swap using the
Hot Swap Control
section
of the
Basic Operation
tab of the GUI. Disabling the hot
swap should turn off the green LEDs (D_PWRGD and
PWRGD) on both the mini evaluation board and the
isolation board.
10.
Manually program the sense resistor value and the ADC
input resistor divider values (for example, R
SENSE
= 1.5 mΩ,
ADC top = 200 kΩ, ADC bottom = 2.8 kΩ). There is no
EEPROM available on the mini evaluation board (
); therefore, these values must be
programmed each time the software GUI is opened.
11.
Check that the voltage and current measurements are as
expected in the
Power Monitor
tab of the software GUI.
