Soldering Guidelines
Any solder re-work to modify the EVM for the purpose of repair or other application reasons must be
performed using a hot-air system to avoid damaging the integrated circuit (IC).

Equipment Interconnect
•
Set the input power supply to 5.5 V(max). Turn the power supply off. Connect the positive voltage lead
from input power supply to V
from input power supply to V
IN
, at the J1 connector of the EVM. Connect the ground lead from the input
power supply to GND at the J2 connector of the EVM.
•
Connect a 0–150-mA load between the output, OUT, at connector J3, and ground, GND, at connector
J4.
J4.
•
Disable the output by jumping JP1, the EN pin to the OFF pin.

Operation
•
Turn on the power supply.
•
Enable the output by jumping JP1, the EN pin to the ON pin.
•
Vary the respective load and input voltage as necessary for test purposes.

Test Results
This section provides typical performance waveforms for the EVM. Actual performance data can be
affected by measurement techniques and environmental variables; therefore, these curves are presented
for reference and may differ from actual results obtained by some users.
