Groundbreaking USB-C technology signals the end of bulky wall chargers

Astute Group offers a world-first in power electronics – a revolutionary USB-C 65W charging module so compact and energy-efficient it can be integrated within wall sockets. This module simultaneously powers several devices without needing multiple chargers and even eradicates the necessity for bulky laptop chargers.

This new technology from Cambridge power innovators Pulsiv and collaborators Innoscience and Frenetic is the world’s smallest – and at >95% efficiency – the world’s greenest 65W USB-C design.

The ultra-compact size of around 32mm x 25mm x 25mm makes this ideal for use with in-wall USB-C sockets, adapters, and chargers. It replaces multiple lower-power 10-15W outputs with one higher-power module capable of charging multiple devices simultaneously – or a 65W laptop straight from the socket without a separate charger.

Other variants will follow, including a 70W design specifically to support the latest Apple MacBook, a 65W design for in-wall solutions optimised for the Japanese/US market (85V-115V input voltage range), and a 140W solution later this year.

The design will be available to customers in three formats:

The complete reference design allows customers to develop the solution according to their needs with minimal design resources and includes a schematic, BOM, EMC test data, Gerbers, and layout files.

The company will offer a fully assembled EMC-compliant module in April to enable rapid prototyping or replace the time/cost associated with manufacturing processes.

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