3.1 Hardware Requirements

For testing purposes, this reference design requires the following equipment:

  • A power supply that is capable of supplying at least 2-A of load and up to 20-V.
  • Current and Voltage Multimeters to measure the currents and voltages during the related tests.
  • The TIDA-050052 board is a printed circuit board (PCB) with all the devices in this design.
  • Resistive load or electronic load that is capable at least 3-A.
  • Thermal camera used to measure the thermal rise of the board during operation.
  • Oscilloscope to capture voltages and a current.
