SAN MATEO, CA, Quantance Inc., manufacturer of the industry's fastest power supply for 4G mobile devices, announced today that it has raised $11 million in Series C funding. Investors include TD Fund, Granite Ventures, InterWest Partners and DoCoMo Capital.

This funding will be used to expand the Quantance family of power management products, including ultrafast power supplies for 4G devices. Quantance's patented and field-tested technology makes faster uplink speeds, improved performance and better network coverage a reality for consumers of smartphones, tablets and data cards. Additionally, the funding will support extension of the company's intellectual property into next-generation products serving broader markets, and enable Quantance to grow its employee base by at least 50 percent this year.

"We are all looking for longer battery life and better data performance from our mobile devices. To achieve this, a power supply must constantly adapt to deliver power only when it is needed, maximizing both performance and economy," said Vikas Vinayak, Quantance's CEO and co-founder. "Yet, batteries and power supplies have not kept up with the consumer's voracious appetite for accessing mobile content and applications when and where they want them. Some generate voltage efficiently, others generate it quickly - but none can do both simultaneously. Quantance's ultrafast power supply bridges that divide to deliver the full promise of 4G wireless and enable the next generation of computer-intensive mobile and server processing."

Quantance's patented technology is based on an innovation that combines highly efficient analog computation with digital switching technology to respond 100 times faster than other current solutions on the market. Conventional power supplies for 4G devices switch at 4MHz. Quantance's technology works at the equivalent of 400MHz without materially reducing efficiency, which commonly happens when speed is increased in conventional power supplies. This extraordinary performance enables 4G devices such as smartphones and tablets to drastically increase upload speeds, improving the user experience and enhancing network capacity.

"Quantance is a performance leader in a booming market that is forecast to consume 10 billion devices over the next eight years," said Eric Zimits, managing director at Granite Ventures. "We look forward to seeing Quantance's patented technology begin to appear in many leading-edge 4G devices. We are also excited to help the company broaden its reach into other markets where we see even greater potential."
