• Loadcapableofsinking1A
• Digitalvoltmeter(DVM)
• Functiongenerator
Procedure
TheEVkitisfullyassembledandtested.Followthesteps
belowtoverifyboardoperation.Caution: Do not turn on
power supply until all connections are completed.
1) Setthepowersupplyatavoltagebetween4.5Vand
60V.Disablethepowersupply.
2) Connect the positive terminal of the power supply
to the VIN PCB pad and the negative terminal to the
nearest PGND PCB pad. Connect the positive ter-
minal of the 1A load to the VOUT PCB pad and the
negative terminal to the nearest PGND PCB pad.
3) Connect the DVM across the VOUT PCB pad and the
nearest PGND PCB pad.
4) Verify that a shunt is installed across pins 1-2 on
jumper JU1.
5) Turn on the DC power supply.
6) Enabletheload.
7) Verify that the DVM displays the expected voltage.
To turn on/turn off the part from EN/UVLO, follow the
stepsbelow:
1) Remove resistors R1 and R2 and the jumper installed
across pins 1-2 on jumper JU1.
2) Connect the power supply to the EV kit and turn on
the power supply. Set the power supply at a voltage
between4.5Vand60V.
3) Connect the function generator output to the
EN/UVLO test loop.
4) EN/UVLO rising threshold is 1.24V and falling thresh-
old is 1.11V. Make sure that the voltage-high and
voltage-low levels of the function generator output are
greater than 1.24V and less than 1.11V, respectively.
5) When powering down the EV kits, first disconnect the
function generator output from the EN/UVLO test loop
and then turn off the DC power supply.

ingtopreventviolationoftheabsolute maximum rating
of the FB/VO pin under short-circuit conditions. Under
