7.6 PCB Footprint Recommendation
The Le9642 is available in a 48 pin QFN package. The package uses a center EPAD for both grounding and heat
dissipation. The Microsemi 48 pin QFN package uses a non-standard narrower pin width versus a standard
package. This is to allow extra clearance between pins. The footprint also specifies a minimum clearance between
the pins and the EPAD (ground)
