About Empower Semiconductor
Empower Semiconductor develops integrated voltage regulators, which are compact power converters that sit close to a processor, and silicon capacitors that store charge on a chip. Placing power conversion near the processor shortens the electrical path, which can improve efficiency for AI chips that draw heavy current. Silicon capacitors are in production, while the regulator programs are being developed with hyperscalers and AI chip makers. Analog Devices announced an agreement in May 2026 to acquire Empower for $1.5 billion in cash. The company is based in San Jose, California.
Empower Semiconductor was founded in 2014 and is based in San Jose, CA, United States. It is listed under ASICs, AI Accelerators. Reported funding is $140M+ Series D (Sep 2025).

What Empower Semiconductor works on
ASICs
An ASIC, or application-specific integrated circuit, is a chip designed to do one job or a narrow set of jobs. Its circuits are fixed when the chip is made. A CPU can run any program; an ASIC does what it was designed for and nothing else.
AI Accelerators
An AI accelerator is a chip, or a part of a chip, designed to run machine learning faster or with less energy than a general-purpose processor. The category includes GPUs, TPUs, neural processing units (NPUs) and chips from many startups.
