Power Integrations EcoSmart® Technology Surpasses $3 Billion in Estimated Energy Savings : Technology Reduces Carbon Emissions by Cutting Power Waste in Electronic Products

Share Article

Power Integrations (Nasdaq:POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, has saved consumers and businesses around the world more than an estimated $3 billion on their energy bills with its EcoSmart energy-efficiency technology. The technology has prevented an estimated 20 million tons of carbon-dioxide emissions from power plants since its introduction in 1998 – roughly equal to the annual emissions of over three million cars.

While alternative energy sources hold great promise for the future, our EcoSmart technology is providing significant savings today without increasing the cost of electronic products.

Most electronic products require power supplies to convert high-voltage AC power from the electrical utility to low-voltage DC power. Power Integrations' EcoSmart chips intelligently manage the flow of power through the power supply, dramatically improving efficiency and reducing standby power waste by up to 95 percent, all without adding to the cost of the end product. Worldwide consumer product and appliance efficiency laws, regulations and voluntary programs are contributing to the replacement of most of the outdated technologies such as discrete electronic components or the notorious copper-and-iron transformers known as "energy vampires." These older technologies deliver power inefficiently, often consuming two or three times the amount of power needed by the end product and wasting substantial amounts of energy while the product is in "standby" or no-load mode, or otherwise not in use.

"Energy savings from our EcoSmart technology are accumulating at an accelerating rate as market uptake of energy-efficient products continues to grow," said Balu Balakrishnan, president and CEO of Power Integrations. "It took seven years to achieve our first billion dollars in savings, and we've reached the three-billion mark just three years later."

"The growing demand for energy and the environmental impact of energy generation are among the greatest challenges facing the world today," added Balakrishnan. "While alternative energy sources hold great promise for the future, our EcoSmart technology is providing significant savings today without increasing the cost of electronic products."

Power Integrations' Green Room web site (http://www.powerint.com/greenroom) contains a wealth of information on the issue of energy waste from inefficient power supplies, as well as a wide range of technical support aids to assist in the design of energy-efficient power supplies. The site also features a comprehensive guide to energy-efficiency standards around the world, and is home to "Mr. Green," a blog chronicling important developments in the area of energy efficiency standards, regulations and other green matters.
