What is Inside
The Evaluation Kit contains:
? ISL9000__EV2 Evaluation board
? The ISL9000 Data Sheet
? The ISL9000EV2 Users Guide (this document)
What is Needed
The following instruments will be needed to perform testing
(not provided):
? DC 6.5V/1A Power supply
? Two Digital Voltmeters (4.5 digit or better).
? Oscilloscope
? 2 channel, 0 to 400mA electronic load
? Cables and wires
Quick Setup Guide
Step 1: Place shunts on J3 between “EN1” and HI”, on J4
between “EN1” and HI”, and on J10 (CPOR). This is
the factory default connection.
Step 2: Set the power supply to 3.8V with a 1.0A current limit
(then turn off).
Step 3: Connect the power supply between VIN and GND
using connector J2.
Step 4: Connect two voltmeter positive leads to the VO1
“kelvin” connector (J13-1, “V1K”) and the VO2
“kelvin” connector (J13-5, “V2K”). The meters can
also be connected to the VO power pins J2-2 and J2-
4 or the banana jacks, but at higher currents, these
won’t reflect the output voltage as accurately as the
kelvin connections.
Connect the negative leads to GND J13-3. (To get
the best representation of the IC output voltage under
all output loading conditions, add a ground terminal
to the GNDk pad and connect the meter ground leads
there).
Step 5: Connect a third voltmeter to the input. This can be
connected to the J2 terminal, but at higher inputs, the
VIk terminal will give the most accurate reading of the
voltage at the ISL9000 VIN pin.
Step 6: (Optional) Connect an electronic load to one or both
of the outputs. For the VO1 output, use the VO1
power connector J2-2 (“V1P”). For the VO2 output,
use the VO2 power connector J2-4 (“V2P”).
Step 7: Monitor VO1and VO2. The voltages should reflect
the voltage of the selected part, i.e. the ISL9000NJ
EV2 board should have 3.3V and 2.8V outputs. For a
complete list of output voltages, see Table 1.
Step 8: Change the loading on each output and monitor the
output voltages
