3.2 Test Setup

Figure 3-1 shows the set up used to test the TIDA-050057. Test tool refers to Intel® VR Test Tool. The following start-up procedure is shown below.

  1. Jump the JP2 and JP4 according to required VID output voltage or connect external drive signals to the TP17 and TP20.
  2. Apply proper DC voltage to J1 and J2. Apply J2 with external power source first and then apply J1 5 V with another power source.
  3. Jump the JP3 to high to enable the device or connect external drive signals to TP18.
  4. Check the output.
