Empower Semiconductor, a leader in advanced power management solutions, has successfully closed over $140 million in Series D financing, led by Fidelity Management & Research Company. Other notable participants in the round include Maverick Silicon, CapitalG, Atreides Management, Socratic Partners, Walden Catalyst Ventures, Knollwood, and a wholly owned subsidiary of the Abu Dhabi Investment Authority (ADIA).
Tim Phillips, Founder & CEO of Empower Semiconductor, highlighted the strength of this syndicate, noting it reflects the company's technological leadership, market opportunity, and robust customer adoption.
Maverick Silicon, a key investor, emphasized Empower's strategic position in the burgeoning AI and data center markets. Andrew Homan, Managing Partner at Maverick Silicon, observed that Empower is effectively addressing a critical bottleneck in modern AI computing. As power demands in data centers continue their upward climb, new technologies become essential for enabling the next generation of AI performance. Empower, consequently, is setting a new industry standard.
Empower Semiconductor's Critical Role in Scaling AI Infrastructure
Empower Semiconductor, based in Silicon Valley, is powering the AI revolution with its FinFast™ technology. This innovation significantly reduces the energy footprint and total cost of ownership for data centers. Their transformational integrated voltage regulators (IVRs) deliver on-demand scalable power with the speed, precision, and signal integrity demanded by today's AI processors. Empower's power-management architecture shrinks solution footprint, height, and component count, achieving vertical power delivery with unprecedented power density and efficiency.
An Integrated Voltage Regulator (IVR) essentially consolidates all discrete power supply components into a single device. Empower Semiconductor develops high-frequency IVRs entirely on advanced CMOS processes. These products fully integrate all power supply discrete components, thereby simplifying the design process and shrinking the PCB area consumed by power management. This approach offers a significant area reduction by consolidating all discrete components.
By leveraging an advanced CMOS geometry platform, Empower Semiconductor products can also integrate directly into a System-on-Chip (SoC) package. This further reduces power area and energy consumption. Compared to traditional power management ICs, Empower’s products enable higher transient accuracy with 100x faster settling times. Furthermore, nanosecond speed Dynamic Voltage Scaling (DVS) can deliver up to 50% energy savings.
Empower IVR products exhibit ultra-fast dynamic voltage scaling—over 1000x faster than current best-in-class power management. This enables processor power state changes in nanoseconds, nearly instantaneously delivering voltage and eliminating excess voltage and wasted power.
