6 NEWS Issue 2 2025 Power Electronics Europe Power Electronics Europe New B511-1C Evaluation Board from Panasonic Industry 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 ultracompact cube or flat module form factor, this GaNoptimised 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. www.pulsiv.com Pulsiv announces the world’s lowest temperature 65-70W USB-C modules Panasonic Industry has announced it recently introduced the new B511-1C Evaluation Board (ENW89861AXKF) which features a PAN B511-1C (ENW89861A3KF) module which is based on the Nordic Semiconductor nRF54L15 single-chip controller. The evaluation board features a pin header in Arduino UNO footprint configurable as shield or board and a mikroBUS socket for easy compatibility with external components like sensors and displays for quick prototyping. It comes with an additional 64Mbit memory on board and a board configuration which is available within Zephyr / nRF Connect SDK. Interested parties can access all the different module interfaces like GPIOs (all 32), NFC-A, current measurement pins, and Segger J-Link on-board debugger easily, which makes the evaluation board ideally suited for the evaluation of the PAN B511-1C module and rapid prototyping of lighting applications, home appliances, industrial sensors, medical devices, healthcare wearables, energy management devices and solar farms. The company says the newly launched small and cost-effective PAN B5111C Bluetooth module from Panasonic Industry features great performance and great memory while minimising current consumption based on the Nordic nRF54L15 single chip controller. A dedicated number of GPIOs is positioned at the edge of the module, with the rest of the GPIOs located at the bottom pad, with the module providing access to all 32 GPIOs of the chip. With its hybrid packaging design of castellated holes and LGA, the module remains at the small size of a 2-cent coin. This way, it combines the advantages of both worlds without compromising on size and enables one of the best pin-to-size ratios for Bluetooth modules currently on the market. http://industry.panasonic.eu
