Summary GaN integration creates a lot of performance leverage. The first steps in integration involve reducing parasitic inductance and integration of drive circuitry. The second stage involves including level shift and current sense. The third stage will include control circuitry in both analog and digital. EPC - The leader in GaN Technology www.epc-co.com 27
