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
