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.

Additional component mounting pads are available to experiment with alternative Cin and Cout

combinations. See Figure 7 for corresponding schematic locations.
