The 2025 International Workshop on Power Supply on Chip (PwrSoC) drew a record 210 global experts to Seoul, underscoring the rapidly growing importance of integrated power technologies for AI, data centres and high‑performance computing. With strong representation from Tyndall National Institute, Irish industry and IDA Ireland, the event highlighted Ireland’s increasing influence in the global semiconductor landscape.
Since its inception in 2008 by Tyndall’s Professor Cian Ó Mathúna, PwrSoC has evolved into the global flagship conference for Power Supply-on-Chip technologies. Co-sponsored by the Power Sources Manufacturers Association (PSMA) and IEEE Power Electronics Society (IEEE PELS), this biennial event has been hosted in leading innovation hubs across the world – including Cork (Ireland), San Francisco, Boston, and Pennsylvania (USA), Madrid (Spain), Taipei (Taiwan), Hanover (Germany), and most recently, Seoul (South Korea) in 2025.
The 2025 workshop brought together participants from Europe, the USA and Asia, with an even split between academia and industry. As the leading international forum for Power Supply-on-Chip technologies, it fosters critical discussions around technology, business, and supply chain challenges and opportunities. These conversations are key to driving progress in the miniaturisation and integration of power conversion and power management solutions. This year’s strong engagement highlights the strategic importance of the conference in addressing current and emerging demands for high‑efficiency power delivery in high‑performance computing, AI and Data Centres, with currents in the range 1,000 to 5,000 amps.
Ireland’s presence at PwrSoC2025 showcased a dynamic blend of cutting-edge research, high-tech entrepreneurship and strategic investment promotion. Delegates included representatives from Tyndall as well as innovative Irish companies, Pulpo Semiconductor – a recent Tyndall spin-out – and Nexalus, a high‑performance thermal management company leveraging licensed technology from Trinity College Dublin. Also in attendance was IDA Ireland, the government agency responsible for attracting foreign direct investment, underscoring Ireland’s commitment to advancing global leadership in power electronics and semiconductor innovation.
Tyndall was represented by Professor Cian Ó Mathúna, Research Programme Director, Integrated Power and Energy Systems; Hugh Smiddy, Head of Business Development; Dr Yi Dou, Senior Researcher, Integrated Power and Magnetics. IDA Ireland was represented by Seamus Carroll, VP and Head of the Semiconductor Unit and Derek Fitzpatrick, Director for Korea and Japan. Their participation focused on engaging Korean and Japanese companies, and promoting Ireland’s ambitious National Semiconductor Strategy, Silicon Island.
At PwrSoC 2025, Intel, NVIDIA and Samsung Electronics delivered plenary talks emphasising the critical role of the conference in addressing the technology and supply chain issues in this age of AI. Meta also presented, showcasing its Orion AR Glasses. The company is closely connected to Ireland’s innovative ecosystem having acquired InfiniLED in 2016 – a micro LED spin-out co-founded by Tyndall’s Brian Corbett – underscoring the global impact of Tyndall’s research.
Tyndall’s collaboration with Taiyo Yuden on large signal characterisation of the company’s state-of-the-art, high‑frequency, ultra-thin chip inductors – operating up to 50MHz – was featured at PwrSoC. The work was presented by Toshio Hiroaka of Taiyo Yuden in the Magnetics Session and by Tyndall’s Dr Yi Dou in the Poster Session.
Commenting on PwrSoC2025, Professor Cian Ó Mathúna said:
The success and longevity of PwrSoC is proof of Ireland’s growing influence in the global semiconductor landscape as we continue to position ourselves as a global partner for advanced semiconductor technologies in integrated power for high‑performance computing, AI and Data Centres.
On the evening prior to the conference, the IDA organised a semiconductor seminar in Seoul which was attended by industry, academia and the Korean press and was opened by Michelle Winthrop, Ambassador of Ireland to Korea.
Tyndall is proud to be a long-standing PSMA and IEEE PELS member, and earlier this year completed a technology report for PSMA on 3D Power Packaging developments focused on Embedded and Integrated Magnetics.
In addition there is a recent interview by Dr Rebecca Pool, Science and Technology Journalist in Power Electronics World with Tyndall’s Professor Cian Ó Mathúna titled, “Industry eyes integrated magnetics for AI chips”.
