Pulsiv USB-C tech claims 95% efficiency

This has been developed in collaboration with the GaN company Innoscience and magnetics expert, Frenetic.

Designs will be released throughout 2024 to support a new class of sustainable USB-C chargers, adapters, and in-wall sockets. The first 65W solution is expected to be announced towards the end of March 2024.

The front-end of the design utilises Pulsiv OSMIUM technology to efficiently manage the AC to DC conversion process with zero inrush current and no input voltage derating. Using an intelligent active valley fill approach, this patented method also enables the use of smaller system components compared to conventional designs.

The DC-DC converter in the 65W variant is based on an industry standard QR flyback. However, when combining a Pulsiv OSMIUM front-end design with optimised magnetics from Frenetic, it is now possible to use an EQ20 core, which provides a 20% reduction in the flyback transformer size.

Three options will be offered:

Reference designs
Complete reference designs will be made available on the Pulsiv website where engineers can download a document package that includes a datasheet, schematic, bill of materials, and EMC test data.

Finished modules
Fully assembled, ultra-compact, and EMC-compliant finished modules will be produced by Pulsiv to demonstrate a size-optimised design and enable rapid prototyping of each reference design. They can also be easily integrated into end products without incurring any further design, development, or manufacturing costs.

Evaluation boards
Evaluation boards will be developed for customers who wish to test and/or adapt the design for their own requirements and will be stocked by a number of distribution partners. A datasheet with schematic, bill of materials, EMC test data, Gerbers, and PCB layout files will also be available.
