Empower Semi debuts AI power delivery platform
Empower Semiconductor, a maker of integrated voltage regulators (IVRs), has announced Crescendo, a vertical power delivery platform designed to address the power demands of AI and high-performance computing (HPC) applications.
Based around the company's proprietary FinFast technology, Crescendo delivers power for upwards of 3,000A power domains, offering a combination of system efficiency, current density and nanoseconds transient response.
For instance, users would see over 8MW reduction in power loss in a typical data centre with 100,000 CPU, compared to traditional architectures, according to Empower.
Crescendo eliminates the capacitor bank and energy storage requirements in existing power delivery architectures by providing energy on demand to the AI chip at high speed and accuracy. Minus the capacitors, Crescendo’s thermally enhanced package can fit in the critical area under the processor to deliver high efficiency, vertically coupled power to the AI chip and eliminate lateral transmission loss.
The FinFast technology is silicon-based combined with novel control architectures, high-frequency magnetics, wide-bandwidth capacitors and power packaging.
“AI’s accelerating power requirements far outpaces the capability of today’s lateral power solutions, both in scale and speed. In developing the Crescendo platform, Empower enables generations of new AI processors to hit their performance goals while running efficiently and cool,” said Tim Phillips, founder and CEO of Empower Semiconductor.
“With this introduction we are enabling efficient true vertical power delivery for our customers – and this is just the beginning, as the Crescendo platform will allow the integration of power delivery directly into the processor at total power supply densities exceeding 5A/mm2, setting Empower apart as the technology leader.”
Empower Semiconductor will be demonstrating the Crescendo platform for the first time at the 2024 OCP Global Summit,mtaking place October 15-17, 2024, in San Jose, Calif.
