San Jose-based Empower Semiconductor has raised over $140 million in its Series D funding round to push forward its FinFast technology for better AI power delivery. Announced on September 22, 2025, this investment aims to scale production and spark new ideas in power solutions for data centers handling massive AI workloads.
Funding Round Highlights
This major funding round drew strong interest from top investors. Fidelity Management and Research Company took the lead, with others joining in to support the company’s growth.
The round included Maverick Silicon, CapitalG, Atreides Management, Socratic Partners, Walden Catalyst Ventures, Knollwood, and a unit of the Abu Dhabi Investment Authority. Barclays Capital handled the placement as the sole agent.
Experts see this as a sign of growing demand for efficient power tech in AI. Data centers now face huge energy needs, and this cash will help Empower meet those challenges head on.
Company Roots and Leadership
Empower Semiconductor started in 2014 in Silicon Valley. Tim Phillips, a long-time expert in semiconductors, founded the company and still leads it as CEO.
Under his guidance, the team has focused on cutting-edge power management. They aim to solve real problems in AI computing, where power efficiency can make or break performance.
The company has grown its tech portfolio over the years. Recent partnerships, like one with Marvell Technology in June 2025, show their push into custom solutions for AI and cloud platforms.
This funding builds on past rounds and sets Empower up for bigger production runs. It reflects trust in their vision to cut energy waste in data centers worldwide.
Phillips shared that the new funds will enable gigawatts of energy savings. This could improve AI platform speeds across global data centers.
FinFast Technology Breakdown
FinFast stands out as Empower’s key innovation for AI power delivery. It uses integrated voltage regulators to provide fast, precise power on demand.
This tech reduces the space needed for power components and boosts efficiency. In AI setups, where processors demand quick energy bursts, FinFast helps avoid waste and downtime.
Compared to older methods, it offers better density and response times. This matters as AI models grow more complex and power-hungry.
Recent reports highlight how data centers could eat up to 8 percent of U.S. electricity by 2030. Solutions like FinFast aim to ease that strain.
Empower’s approach also shrinks the overall footprint of power systems. This leads to lower costs for operators building massive AI infrastructure.
- Delivers scalable power for high-performance AI chips.
- Cuts energy use in hyperscale data centers.
- Improves signal integrity for faster data processing.
- Supports vertical power delivery to save space.
