3.2.1 Test Setup

This section describes how to properly connect the setup of the TIDA-050033.

  • Connect the positive terminal of DC power supply to pad BUS, and its GND terminal to pad GND on PCB.
  • Connect the positive input of the E-Load to pad 12 V, and its GND input to pad GND on PCB.
  • Keep the DC power supply and E-Load off. Set the DC power supply to 13 V and E-Load to 200mA for 5ms, 25mA for 995mA.
  • Turn on the DC power supply and E-load.
  • After the super capacitor is charged to 2.5 V, turn off the DC power supply.
