Pulsiv fires the gun on USB-C modules for wall socket power

UK power startup Pulsiv has developed 65W and 70W power modules with a thermal profile low enough to fit into wall sockets and furniture.
This is a key area to replace the millions of USB-C power adapters and follows a 65W reference design launched back in August 2024.
The USB-C modules are developed specifically for installed applications such as wall sockets, desks and furniture with an operating temperature of just 32°C (max) above ambient with an efficiency 97.34% and zero inrush current.
The modules have used the Pulsiv architecture to solve the challenges relating to heat, size and safety for integration into a wall socket with limited air flow for cooling, This needs high efficiency and low temperature operation at full load to ensure a long lifetime.
The modules can operate at full load for more than 8 hours continuously where thermal stability is achieved.
The modules combine the Pulsiv Osmium optimized power factor correction (PFC) technology with an industry standard QR flyback converter to safely deliver 65W or 70W (MacBook-compatible) and are available in an ultra-compact cube or flat module form factor.
The Osmium controller is a standard secure microcontroller that implement Pulsiv’s valley fill algorithms. This algorithm allows a half active bridge that can be difficult to implement at low current but helps boost the efficiency to 95% with a peak of 96%.
The modules will be shown at the PCIM power exhibition in Nuremberg, Germany, in May 2025.
