Quick Start Procedure

  1. Connect the power supply between VIN and GND connectors using short wires.
  2. Connect the load of converter between VOUT and GND connectors using short wires.
  3. Connect the voltmeter 1 between VIN_S(TP1) and GND(TP2) to measure supply voltage (VIN)

  4. Connect the voltmeter 2 between VO_S(J6) and GND(TP3) to measure output voltage (VOUT)

  5. Set the supply voltage (VIN) at an appropriate level between 6 V to 80 V. Set the current limit of the supply to an appropriate level as well.
  6. Turn on the power supply. The EVM powers up and provides VOUT = 5 V.
  7. Monitor the output voltage while increasing the load current to 2.5-A maximum.

See Figure 2-1 for the location of the connectors and test points.
