Transphorm teams for 100W GaN Quick Charge adapter
Transphorm has teamed up with Salom to develop a 100W GaN power adapter for the Qualcomm Quick Charge 5 specification
The USB-C Power Delivery (USB-C PD) charger will pair with the Quick Charge 5 technology capable of charging smartphones from 0 to 50 percent in five minutes. The universal adapter, available by the end of the year, will support power delivery modes as well as 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, 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 FET 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,” said Joseph Reisinger, President, Salom America. “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.”
