Use the following procedures for line and load regulation measurement:

1. Connect the electronic load (+) to J5 and electronic load (–) to J1 and J7 (Figure 6-1).
2. Ensure that the electronic load is set to draw 0 A_DC.
3. Ensure the jumper provided on the EVM shorts on J2 and J6 before V_IN is applied.
4. Connect input power supply (+) to J3 and input power supply (–) to J4 (Figure 6-1).
5. Increase V_IN from 0 V to 12 V using the digital multimeter to measure input voltage.
6. Remove the jumper on J2 and J6 to enable the controller.
7. Use the other digital multimeter or the oscilloscope to measure output voltage V_OUT at TP14 and TP3.
   Table 8-1 List of Test Points for Line and Load Measurements

   Test Point	Node Name	Description
   TP14	VOUT	Sense VOUT+ locally across C9. Use for load and line measurements
   TP3	GND	Sense VOUT– locally across C9. Use for load and line measurements
   TP16 or TP18	VIN	Sense VIN+ across C14 or C26
   TP35 or TP33	GND	Sense VIN– across C14 or C26

8. Vary the load from 0 A_DC to the maximum rated output of 80 A_DC. V_OUT must remain in regulation as defined in Table 3-1.
9. Vary V_IN from 5 V to 16 V. V_OUT must remain in regulation as defined in Table 3-1.
10. Decrease the load to 0 A.
11. Put the jumper back on J2 and J6 to disable the converter.
12. Decrease V_IN to 0 V or turn off the supply.
