WEBINAR: Simple Layout Steps for Maximizing GaN Design Performance
• Designing with GaN is not difficult- Many similarities to MOSFET- Differences require attention to
detail but no new concepts
• Common “first-time” mistakes- Missing Kelvin source- Absence of power loop flux
cancellation- Poor gate loop
• Many resources available- Easy to find- Easy to use- GaN Systems application engineering
