TEST ASSEMBLY
EQUIPMENT NEEDED
1. Power Supply
2. Function Generator
3. Oscilloscope
4. Proper heatsinking system (if operating at high current).
TEST SETUP
Connect the power supply to +V
S
and ‐V
s
ports. If you wish to use boost supply, connect boost voltage
supplies to +V
B
and ‐V
B
ports. Otherwise, short +V
S
to +V
B
and ‐V
S
to ‐V
B
. Refer to product data sheet for volt‐
age specifications. Connect the BNC cable from the function generator to either P1 port for inverting configu‐
ration or to P2 for non‐inverting configuration. Connect a 5V DC supply to P16 port for over current flag.
Do not plug in EK91‐1 board yet. First power on the input signal and power supplies. Measure voltages on
all pins on J1A and J1B on the DUT side to ensure that there is no short and to check if all the pins read correct
voltages.
Now, mount the EK91‐1 on EVAL 164. If connecting a resistor load, connect between ports P11 and P10. if
a snubber circuit is connected, connect a reactive load between P12 and P10. Input and output waveforms
can be checked on an Oscilloscope by connecting it to the test points mounted on the board. Begin the test
with minimum values of input and supply voltages.
