2.1.4.2 Basic Test Procedure

  1. Set up the EVM, USB2ANY, and Configuration GUI as previously described. Do not enable the converter.
  2. Set the load to constant-voltage (CV) mode and set to 22V.
  3. Set the current limit of the input supply to 0.1A maximum.
  4. Set the input source 48V and turn on.
  5. Enable the converter by I2C. The load voltage must be within the 20V regulation target.
  6. Set the current limit of the input supply to 7A maximum.
  7. Set the load voltage to 19V. The load current must be within the 5A regulation target.
  8. Set the load voltage to 12V. The load current must be within the 5A regulation target.
  9. Set the load voltage to 22V. The load voltage must be within the 20V regulation target and the load current must be 0A.
  10. Disable the Converter by I2C.
  11. Turn off the input power source.
