Dublin, CA, 03/03/2025 – Amber Semiconductor (AmberSemi) is set to debut a breakthrough DC-DC power conversion solution at APEC 2025, targeting efficiency gains for artificial intelligence (AI)-driven data centers. By removing many conversion steps, the company’s new 50VDC to 0.8VDC converter delivers power straight to higher density and efficiency AI chips on server motherboards.
New chances to solve problems with efficiency, current density, and voltage control have emerged from the continuous development of power distribution solutions in modern computing and automotive systems. Particularly for data centers, a top strategy in this transition is the creation of vertical power supply systems that provide increased efficiency and scalability. Designed in cooperation with leading data center operators, AmberSemi quotes that its vertical-based solution increases efficiency from 81% to over 90%, resulting in projected $4 billion in annual energy savings and a 15-million-ton COâ‚‚ emissions reduction in the United States alone.
AmberSemi CEO Thar Casey highlights in an exclusive interview with Power Electronics News the growing power demands of AI, with rack power soaring from 10kW to over 200kW. He emphasized that AmberSemi’s approach addresses the entire power system architecture rather than isolated components, integrating advancements in semiconductor materials, power conversion, and control.
