MILPITAS, Calif.—Empower Semiconductor recently reported the production release of its EP70xx series of devices, aimed at driving a dramatic reduction in power consumption in data centers globally.

The family of high-performance power management integrated circuits (ICs) uses Empower’s technology to eliminate all external components, resulting in “the smallest and highest performance solution in the industry,” the company said in a release. Empower Semiconductor is the provider of what it called “the first and only Integrated Voltage Regulator (IVR).”

“Customers have embraced this incredible technology developed by our world class team,” said Tim Phillips, CEO and founder of Empower Semiconductor, in the release. “We are excited to bring the EP70xx IVR family to volume production with the ability to deliver in short lead times due to our unique configurable product platform.

“We have a full production ramp prepared to support customers’ existing and new designs,” Phillips continued. “The combination of density, speed, and efficiency is allowing designers to utilize our products in groundbreaking ways, enabling breakthrough levels of system performance.”

The exponential increase in the amount of data being communicated and processed around the globe is driving the energy consumption of data centers and communications networks to 17 percent of total electricity demand worldwide by 2030, according to an article published in Nature, “How To Stop Data Centers From Gobbling Up The World’s Electricity” (September 12, 2018). The result is a dramatic increase in pollution, carbon emissions, and cost.

Empower Semiconductor was founded with the mission to “minimize the energy footprint of the digital economy” by developing novel fully integrated power management solutions that increase the performance and reduce power consumption of energy-hungry, data-intensive applications.

With its product platform, the EP70xx, Empower has achieved the total integration of a triple-output DC/DC power supply, with no external components, into a single tiny 5mm x 5mm package. The result is up to 10 times higher current density, 3 times tighter accuracy during transients, and 1,000 times faster dynamic voltage scaling (DVS) than leading competitors, the company said in the release.

The ExpressV™ DVS is reported to be capable of scaling voltage by +/-10mV/ns, delivering up to 50 percent energy savings in processor-intensive applications compared to traditional power management.

“Data center power continues to limit the full potential of the cloud as the industry struggles with power and cooling within compute, networking, and storage,” said Alan Weckel, founder and technology analyst at 650 Group, in the release. “As the industry moves towards AI and ML workloads and edge computing, Empower’s industry-leading power density and performance will help drive future designs and unleash a new wave of cloud computing in the data center.”

The Empower IVR™ offers what its developer called “the world’s fastest load transient response.” It is said to regulate through a 0 to 10A load step in 500ns with <15mv droop, with zero output capacitors. It features nearly flat efficiency curves up through maximum load due to the unique architecture, allowing designers to maximize the output power capability from any single output. The patented digitally configurable hardware platform has simplified the adoption of DC/DC converters, according to Empower.

With a single footprint, no external components, and extensive programmability, including a wide range of current and output configurations, the EP70xx is said to “proliferate across nearly all designs and platforms.” By having multiple entire power supplies in a single IC package, it is said to eliminate or significantly reduce the traditional concerns of component variation and sourcing, synchronization, and stability.

“Because we can support high-volume production orders within a 10-week lead time, we have seen customers take advantage of the quick and simplified design process with the assurance of a short delivery time,” said Steve Shultis, senior vice president of worldwide sales and marketing at Empower Semiconductor, in the release. “Support for the EP70xx IVR series includes expert field and factory resources, reference designs, and design tools that allow customers to rapidly move to prototyping. The easy-to-use GUI is utilized to program the device via the I3C/I2C port during operation.

“Just like that, you have three outputs tightly regulated at high currents with wide bandwidth,” Shultis continued. “No input filter design, no output filter design, no feedback resistors, no loop compensation design, no component changes.”

EP70xx devices are available with a choice of triple, dual, or single-regulated outputs. Output currents range from 1A to 10A. The packaging options include a low profile 5mm (L) x 5mm (W) x 0.75mm (H) FcCSP package or a 10mm (L) x 8mm (W) LGA option that is reported to be 3-5 times thinner than traditional integrated power modules.
