The long-expected first GaN-on-Sapphire die has been integrated into a commercially-available device!

This report unveils Power Integrations’ technical choices from the device design up to the packaging.

The first GaN-on-Sapphire-based Power Integrated Circuit (IC) die has been found in the Wall-Charger PowerPort Atom PD1: A2017 from Anker. The die is co-packaged with three ICs constituting primary-side and secondary-side controllers in the SC1933C device.

To our great surprise, the power GaN HEMT was processed on a sapphire substrate which is a major breakthrough that we did not observe before in other power GaN HEMTs. The latter being generally processed on Silicon substrates.

This report presents a deep teardown analysis of the SC1933C. Detailed optical and Scanning Electron Microscope pictures and cross-sections with energy-dispersive X-ray analysis are included to reveal Power Integrations’ technical choices at the microscopic level of the IC and HEMT designs.

The report provides an estimation of the production costs of the ICs, the HEMT and the package as well as the estimated selling price of the component. Finally, the report includes a comparison with the GaN-on-silicon HEMT from Navitas. This comparison highlights the differences in GaN die designs and manufacturing costs.

A system-oriented analysis of the PowerPort Atom PD1: A2017 from Anker, can be found in our “GaN Chargers Comparison” report, which focuses on the impact of GaN die adoption in the latest wall charger designs and their performance.
