Power Integrations, Inc. operates in the Semiconductors and related devices sector. Power Integrations, Inc. designs, develops, manufactures, and markets high-voltage, analog and mixed-signal integrated circuits products (ICs). It offers both monolithic (a single chip in an IC package) and hybrid (multiple chips in a single package) IC products. It also offers a range of high-performance, high-voltage silicon diodes. Its ICs and diodes are used in electronic power supplies, also known as switched-mode power supplies or switchers. As of December 31, 2010, it offered IC products that can be used in alternating current-direct current (AC-DC) power supplies with output wattages ranging from less than one watt up to approximately 500 watts. Its ICs can be used in virtually any power-supply application, and power supplies focused for the communications, consumer, computer and industrial end markets. During the year ended December 31, 2010, it purchased the assets of an early-stage research and development company, and acquired Qspeed Semiconductor Inc. In our complete report available for purchase the company is compared to: IPG Photonics Corp, Tessera Technologies Inc and Lattice Semiconductor Corporation.
