Inductor current can be monitored by connecting a loop of between module pin 7 (Vout) and the Co array.
First cut the top side conducting etch between the two vias adjacent to pin 7, then install a 5” loop of 22 ga
insulated wire in the two vias. Monitor the inductor sense loop with an AC/DC oscilloscope current probe.

The Vin input plane has solder mask openings where an input LC network can be placed to accommodate
improved differential mode and conducted EMI performance.
