Make sure that Jumper 2 is open. Power on the board
(output voltage is at 1.8 V).
If Jumper 1 is shorted, replace the inductor to another
value to fit 600 kHz operation.
If Jumper 3 is shorted, the output high margining is at
1.89 V. If Jumper 4 is open, the output low margining is at
1.71 V.
Verify the output voltage tracking features when
connecting the external generator to the TRKN point.
Use the PWGD point for monitoring operation behavior.
