2.1 Equipment

This section includes a list of supplies required to perform tests on this EVM.

  1. Power Supply #1 (PS1): A power supply capable of supplying 5 V at 3 A is required. While this part can handle larger voltage and current, it is not necessary for this procedure.

    Power Supply #2 (PS2): A power supply capable of supplying 5 V at 1 A is required.

  2. Loads: Load #1 (4-Quadrant Supply, Constant Voltage < 4.5 V): A "Kepco" Load, BOP, 20-5M, DC 0 to ±20 V, 0 to ±5 A (or higher).

    Alternative Option: A 0–20 V/0–5 A, > 30-W DC electronic load set in a constant voltage loading mode.
  3. Meters: (4x) "Fluke 75" multimeters (equivalent or better).
  4. No software is required to test this part.
