Pulsiv Limited, the Cambridge (UK) innovator of power electronics technology has announced the delivery of 240W from a single USB-C port. This ground-breaking achievement has been developed by combining a Pulsiv OSMIUM front-end design with an industry standard flyback which passes strict EMC/Line Current requirements.
Existing 240W USB-C chargers distribute the power across multiple ports with a maximum of 140W being delivered from a single 1C port. This leaves many higher power applications such as monitors, gaming laptops, and small domestic appliances unable to benefit from the common USB-C interface and fast-charging protocol. Traditional Boost PFC+LLC based designs are notoriously noisy, so EMC compliance can be a challenge. They are also expensive and do not respond well to variable output voltages or rapidly changing load requirements. Pulsiv OSMIUM technology enables a flyback topology to be used at higher power levels which solves all of these problems.
Delivering 240 Watts of power has an immense impact on reducing the charge time of virtually all battery-powered products. Chief Product Officer at Pulsiv, Dr Tim Moore, who was also former Chief Technology Officer at consumer brands, SharkNinja and GHD, understands this more than most and comments: “The small domestic appliance market has been anxiously waiting for USB-C technology to achieve higher power levels. Cordless power/garden tools, vacuums and portable kitchen appliances are just a small selection of products that can benefit from super-fast efficient USB-C charging. With battery technology already well advanced, 240W enables charge times to be reduced by up to 80%, smashing charge anxiety and driving a new paradigm for small domestic appliances.”
Pulsiv’s Director of Global Sales, Nick Theodoris has been collecting valuable feedback from customers around the world and adds: “240W USB-C is causing huge excitement in the industry. Manufacturers of in-wall sockets, in-desk solutions, and after-market chargers can now bring new levels of charging within existing products, but this further enables them to develop entirely new solutions too. However, the interest doesn’t stop there. Applications such as televisions, monitors, projectors, and games consoles which don’t require charging, can benefit from 240W USB-C power supplies. It enables the entire power electronics to be removed from the product which significantly reduces the overall size, weight, and cost. We’re expecting to uncover even more applications which can benefit from our ground-breaking solution and the level of interest so far has been unprecedented. I’m looking forward to how Pulsiv will completely redefine the fast-charging space.”
The company’s strategy for deploying its technology adds further flexibility for customers. Three options are set to be offered:
- Reference Design. A reference design containing a datasheet, schematic, and bill of materials will be published on www.pulsiv.com in the coming weeks. This will enable anyone to start designing and laying out their own 240W USB-C solution and become one of the first in the world to adopt 240W USB-C.
- Standard Assembled Module. For those whose resources and time are limited, Pulsiv will offer a standard fully assembled module with 1 x USB-C connector. The specification and design of this standard module has already started and pre-orders for samples can be placed now for delivery in late March 2025, with mass production quantities being delivered from July 2025 onwards. A number of Pulsiv’s distributors, including Digikey, will also stock the standard modules for fast delivery to customers globally.
- Custom Assembled Module. For anyone that has more specific requirements, custom assembled modules will also be offered. This enables customers to determine their own specification, which can include the number and location of USB connectors, input voltage range, and any specific mechanical form factor requirements. This flexible option will come with an NRE of just $10,000 and an MOQ of 500pcs providing a very reasonable entry point for everyone.
