This overview covers the final step in the planar transformer design process using PI Expert's Magnetics Designer tool. After defining the stack-up and winding parameters, users can optimize the transformer’s form factor by adjusting the pin area, repositioning pins, and refining PCB dimensions. The tutorial explains how parameters such as XP1, XP Left, and XP Right determine the available pin area and can be modified to create a more compact layout.

The video also demonstrates how to move individual pins, adjust pad and hole diameters, and ensure pin placements remain within the defined pin area. Once pin locations are finalized, users can further reduce the PCB footprint by modifying enclosure dimensions, including the XP and EP1 parameters. These steps complete the planar transformer design process and prepare the design for manufacturing export.
