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, 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.
