3.1.2 Test Procedure

  1. Set the power supply current limit to 35A. Turn off the power supply. Connect the positive output of the power supply to J1 and the negative output to J3.
  2. Connect the load to J2 for the positive connection and J4 for the negative connection.
  3. Set the power supply voltage to 9V and the electronic load to 0.1A. The electronic load voltage must be in regulation with a nominal 12V output.
  4. Slowly increase the load while monitoring the output voltage between J6-VOUT and J6-GND. The voltage must remain in regulation with a nominal 12V output as the load is increased up to 17A.
  5. Slowly sweep the input voltage from 9V to 30V. The output voltage must remain in regulation with a nominal 12V output.
  6. Slowly sweep the input voltage from 30V to 9V. The output voltage must remain in regulation with a nominal 12V output.
  7. Decrease the load to 1A.
  8. Decrease the input voltage down to 0V to shut down the Buck-Boost controller, and then turn off the load.
