Test Procedure
Step 1: Set the power supply current limit to 1 A. Turn off the power supply. Connect the positive output of
the power supply to J1 and the negative output to J2.
Step 2: Connect the load to J3 for the positive connection and J4 for the negative connection.
Step 3: Set the power supply voltage to 9V and the load to 0.1 A. The electronic load voltage must be in
regulation with a nominal 12 V output.
Step 4: Slowly increase the load while monitoring the output voltage between TP3 and TP4. It must
remain in regulation with a nominal 12 V output as the load is increased up to 10 A.
Step 5: Slowly sweep the input voltage from 6 V to 36 V. The output voltage must remain in regulation
with a nominal 12 V output.
Step 6: Turn off the load, and decrease the input voltage down to 0 V to shut down the buck-boost
converter, and then turn on the load to discharge the output capacitors.
