Pulsiv, a UK innovator of power electronics technology, has announced the release of a series of 65W-70W USB-C modules. Aimed at installed applications such as wall sockets, desks, and furniture, the company says these ultra-compact and fully assembled modules achieve the world’s lowest operating temperature of just 32°C above ambient with an industry leading efficiency 97.34%.

The problem

USB-C charging in wall sockets, desks, and furniture typically offer power levels of 15-30W and often struggle to handle multiple devices and/or fast charging. Limitations on physical size and natural airflow cause higher power solutions at 45W-65W to reach temperature levels in excess of 80°C above ambient causing the power supply to either reduce the power to 15W, or in many cases, cut off altogether.

The solution

Pulsiv says its fully assembled USB-C modules have solved all the challenges relating to heat, size and safety, making it the only suitable solution for installed applications. It combines Pulsiv OSMIUM optimised PFC technology with an industry standard QR flyback to safely deliver 65W or 70W (MacBook compatible). Available in an ultra-compact cube or flat module form factor, this GaN-optimised design can operate continuously for more than 8 hours at 100% load and never exceed 32°C above ambient.

The company says furthermore, due to its unique and patented switching method, there is zero inrush current – eliminating the problems caused by power outages where multiple USB-C wall sockets have been installed in a single location.

Pulsiv’s Chief Product Officer, Dr Tim Moore has been managing the development of the modules and comments: “USB-C provides a common interface for all consumers, but combining convenient and fast charging is technically very challenging for manufacturers of installed applications. Many customers we’ve engaged with have expressed their concerns regarding the managing of heat when looking to adopt higher power levels, especially in wall sockets where space is limited and safety regulations are stringent. Our fully assembled modules provide a fast and easy method for companies to integrate USB-C fast charging at 65-70W without the need for managing the entire manufacturing process. It’s thanks to Pulsiv OSMIUM technology that we’ve become the first company in the world to solve this problem and deliver the only suitable solution for installed applications which can operate for extended periods while maintaining an ultra-low temperature. We know that this is an exciting and rapidly growing market which promises to change how we think about the charging of mobile phones and laptops and will redefine the fast charging of domestic appliances and gardening tools.”
