Operations and Sustainability

Powering Our Operations with Renewable Energy

In August 2010 we switched on a 600-kilowatt solar array at our San Jose headquarters facility. The $3.6-million system generates enough power to effectively take one of our two buildings off the grid, with enough left over to power our parking-lot lights. Among the ten largest commercial solar installations in Silicon Valley at the time of its completion, the system is expected to prevent more than 10,000 tons of CO₂ emissions over 25 years and save Power Integrations approximately $180,000 per year on its energy bills.

To limit energy consumption, we employ automatic management of heating, cooling and lighting in our offices, and encourage a culture of efficiency among our employees. In 2011 we completed a datacenter efficiency project resulting in virtualization of more than 90% of our servers. We estimate that this project will save more than five million kWh over five years, resulting in hundreds of thousands of dollars in savings and preventing thousands of tons of CO₂ emissions.

Responsible Supply Chain

As a fabless semiconductor company, Power Integrations views our supply chain partners as an extension of our operations. We have a rigorous qualification process for suppliers and choose established, high-quality manufacturers; all of our wafer foundries and assembly sub-contractors are ISO 14001 certified for environmental compliance and ISO 9001 certified for quality management.

We audit our suppliers annually, and ensure that they follow local regulations for labor practices and environmental protection.

Also, in order to lower the cost and environmental impact of delivering our product from the factory to our customers, Power Integrations has chosen manufacturing vendors located near our customers.

Low-Impact Materials Use

As part of our environmental policy, Power Integrations complies with, and often exceeds, U.S. and international regulations on hazardous materials in our products.

• All Power Integrations products are lead-free, and comply with the EU's Restriction of Hazardous Substances (RoHS) directive.
• All of our products also comply with REACH, another EU regulation which assesses the risks of chemicals to human health and the environment, and controls their inclusion in products.
• An increasing number of our products are fully "green," meaning that they comply with the RoHS standards and are also halogen-free.
