Empower Semiconductor, a wholly owned subsidiary of Analog Devices since July 2026, develops integrated voltage regulators (IVRs) and power management solutions for AI compute and high-performance computing. Its proprietary FinFast™ technology delivers ultrafast transient response, high power density and vertical power delivery for AI and HPC processors. The Crescendo vertical power delivery platform provides scalable on-demand power for applications requiring 3,000A+ power domains, with roughly 20x faster transient response than traditional solutions. Empower's silicon capacitors are in production, and it works with leading chipmakers and hyperscalers on data-center power efficiency.
