What’s Inside
The Evaluation Board Kit contains the following materials:
? The ISL6244 EVAL Board
? The ISL6244 Evaluation Board document
What is Needed
The following materials will be needed to perform testing:
? 1 to 2 electronic loads [see note]
– 0-25V @ 15A (+VDC)
– 0-5V @ 5A (+5V)
– 0-12V @ 1A (+12V)
? precision digital multi-meters
NOTE: amperage rating of power supplies are determined by
maximum expected loading plus a percentage margin of error
Quick Setup Guide
Step 5:
Step 6:
Step 7:
Step 8:
Step 9:
Set the 0-12V power supply to +12V and place in
the “STANDBY” or “OFF” position. Connect the
positive terminal (+) of the supply to the +12V
terminal J6 and the negative terminal (-) of the
supply to GND J8.
Connect the positive terminal (+) of a DMM to the
+5V terminal J5 and the negative terminal (-) to the
GND terminal J7.
Connect the positive terminal (+) of the electronic
load to the VOUT terminal J1. Connect the
negative terminal (-) of the electronic load to the
GND terminal J2. Make sure the electronic load is
set to the 0A condition.
Connect the positive terminal (+) of a DMM to the
VOUT test point TP13 and the negative terminal (-)
to the GND test point TP14.
Check to ensure all jumpers and switches are in
their default positions prior to application of power
(refer to“Detailed Description of Jumper Settings”
Step 1:
Set the 0-5V power supply to +5V and place in the
and “Detailed Description of Switch Settings” ).
“STANDBY” or “OFF” position. Connect the
positive terminal (+) of the supply to the +5V
terminal J5 and the negative terminal (-) of the
supply to GND J7.
Step 10:
Step 11:
Set all power supplies to the “ON” position. LED
CR1 should show Red. Check all DMM displays for
correct voltage levels. Adjust if necessary.
Turn the ENABLE switch SW2 to the “ON” position.
Step 2:
Step 3:
Connect the positive terminal (+) of a DMM to the
+5V terminal J5 and the negative terminal (-) to the
GND terminal J7.
Set the +VDC power supply to +19V and place in
the “STANDBY” or “OFF” position. Connect the
positive terminal (+) of the supply to the +VDC
terminal J3 and the negative terminal (-) of the
supply to GND J4.Connect the load
LED CR1 should show Green. The VOUT DMM
should read 1.60V ( ± 1%).
At this point the board has been properly powered up.
Normal testing can begin.
