San Jose, CA — May 12, 2009 - Power Integrations, the leader in high-voltage integrated circuits for energy-efficient power conversion, today introduced a new online tool that enables designers of external chargers and adapters to instantly determine whether their product complies with worldwide energy-efficiency regulations. The new External Power Supply Efficiency Compliance Calculator quickly and easily compares power supply performance measurements against the maze of specifications that now apply to external chargers and adapters, significantly simplifying the design engineer's task of verifying compliance. The calculator currently checks compliance to the following standards:

Comments Rich Fassler, manager of energy-efficiency programs at Power Integrations: "Energy-efficiency specifications and standards have become increasingly complicated, and the landscape is constantly changing. For example, in April 2009 alone, two important updates occurred -- the EC Code of Conduct issued version 4 of its specification, and the upcoming EC Eco-design standard was approved by European Parliament."
