Pulsiv enables 240W from a single USB-C port

Pulsiv in the UK has developed the first power charger to supply 240W from a single USB-C port.

The design combines the Pulsiv Osmium front-end design with an industry standard flyback which passes strict EMC/Line Current requirements.

The 240W design can be used for in wall power sockets, monitors, gaming laptops, TVs and small domestic appliances.

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 unable to benefit from the common USB-C interface and fast-charging protocol.

Traditional boost designs with a power factor correction (PFC) front end and resonant LLC converter are notoriously noisy, so EMC compliance can be a challenge at this higher power level. The designs can also be expensive and do not respond well to variable output voltages or rapidly changing load requirements. The Osmium technology enables a flyback topology to be used at higher power levels.

Pulsiv is offering three options for the 240W USB-C technology following 75W and 100W USB-C designs.

Pulsiv will also 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.

For 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 engineering fee of$10,000 and an MOQ minimum order of 500pcs.

“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,” said Tim Moore, chief product officer at Pulsiv who was formerly Chief Technology Officer at consumer brands SharkNinja and GHD.

“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.”

“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,” said Pulsiv’s Director of Global Sales, Nick Theodoris.

“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.”
