Test Procedure

  1. Set the power supply current limit to 10A. 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 16V and the electronic load to 0.1A. The electronic load voltage must be in regulation with a nominal 16V output.
  4. Slowly increase the load while monitoring the output voltage between J6-VCC and J6-GND. The output voltage must remain in regulation with a nominal 16V output as the load is increased up to 9.4A.
  5. Slowly sweep the input voltage from 16V to 36V. The output voltage must remain in regulation with a nominal 16V output.
  6. Decrease the load to 2.5A.
  7. Slowly sweep the input voltage from 36V to 5V. The output voltage must remain in regulation with a nominal 16V output.
  8. Decrease the input voltage down to 0V to shut down the buck-boost converter, and then turn off the load.
