Universal GaN Power Adapter to Leverage Qualcomm� Quick Charge� 5 Technology, Designed to Charge Smartphones from 0 to 50 Percent in 5 Minutes

GOLETA, Calif.--(BUSINESS WIRE)--$TGAN #5G--Transphorm, Inc. (OTCQX: TGAN)�a pioneer in and global supplier of high reliability, high performance gallium nitride (GaN) power conversion products�today announced a collaboration with power solutions manufacturer Salom to bring to market a Quick Charge 5 compliant 100 watt GaN power adapter that is slated for release in Q4 2021.

The new USB-C Power Delivery (USB-C PD) charger will pair with Quick Charge 5 technology�capable of charging smartphones from 0 to 50 percent in five minutes.* It will be a universal adapter offering the traditional power delivery mode and the USB-C programmable power supply (PPS) mode version 3.0, which enables the charger to easily deliver a sliding range of voltages (between 3.3 V to 21 V) versus the traditional mode�s stepped voltage output.

With assistance from Qualcomm Technologies, Inc., Transphorm developed the adapter�s specification and designed the overall functional product, from the universal input through to the USB-C PD/PPS output. Transphorm�s GaN is used in the traditional AC-to-DC boost PFC and the DC-to-DC quasi-resonant flyback (QRF) topologies. Salom was responsible for then taking that designed system, fine tuning it, developing its enclosure and completing all the required certifications such as Quick Charge 5, conducted/radiated emissions, touch temperature, and others.

�Adapter solutions with Transphorm�s GaN enable more with less,� said Philip Zuk, SVP of Worldwide Technical Marketing and Business Development, Transphorm. �Compared to other GaN solutions such as e-mode, our normally-off SuperGaN� FETs offer ease of design and standard Silicon-like drivability while delivering more power in a considerably smaller footprint without compromise. And we�ve proven that our production yields can meet high volume requirements. We�re proud to work with Salom to deliver this Quick Charge 5 compliant charger. To utilize such revolutionary technology is an incredible honor and a testament to our teams� engineering achievements and collaboration.�

�We were able to go from concept to production in a short time,� added Joseph Reisinger, President, Salom America Co. �The collaboration and commitment demonstrated by Transphorm and Salom has been strong. We trust that the resulting USB-C PD/PPS charger will prove to be one of the most reliable available today and will enable consumers to truly experience a fast, easy charging experience.�
