Power Integrations Inc.

Power Integrations, Inc. designs, develops, manufactures, and markets analog and mixed-signal integrated circuits (ICs), and other electronic components and circuitry used in high-voltage power conversion worldwide. The company offers a range of alternating current to direct current power conversion products that address power supply ranging from less than one watt of output to approximately 500 watts of output for mobile-device chargers, consumer appliances, utility meters, LCD monitors, main and standby power supplies for desktop computers and TVs, LED lighting, and other consumer and industrial applications. It also provides high-voltage diodes; and high-voltage gate-driver products under the SCALE and SCALE-2 product-family names. In addition, the company offers motor-driver ICs for use in refrigerator compressors, ceiling fans, and air purifiers, as well as pumps, fans, and blowers used in consumer appliances, such as dishwashers and laundry machines. It serves communications, computer, consumer, and industrial markets. The company sells its products to original equipment manufacturers and merchant power supply manufacturers through sales personnel, as well as a network of independent sales representatives and distributors. Power Integrations, Inc. was founded in 1988 and is headquartered in San Jose, California.

Vishay Intertechnology Inc.

Vishay Intertechnology, Inc. manufactures and supplies discrete semiconductors and passive electronic components in Asia, Europe, and the Americas. The company operates through six segments: Metal Oxide Semiconductor Field Effect Transistors (MOSFETs), Diodes, Optoelectronic Components, Resistors, Inductors, and Capacitors. It offers semiconductor components, such as low- and medium-voltage TrenchFET MOSFETs, high-voltage planar MOSFETs, high voltage super junction MOSFETs, power integrated circuits, and integrated function power devices; rectifiers, small signal diodes, protection diodes, thyristors or silicon-controlled rectifiers, and power modules; and standard and customer specific optoelectronic components, such as infrared (IR) emitters and detectors, IR remote control receivers, optocouplers, solid-state relays, optical sensors, light-emitting diodes, 7-segment displays, and IR data transceiver modules. The company also provides passive components, including resistors, inductors, and capacitors. Its semiconductor components are used for power control, power conversion, power management, signal switching, signal routing, signal blocking, signal amplification, two-way data transfer, one-way remote control, and circuit isolation functions; and passive components are used to restrict current flow, suppress voltage increases, store and discharge energy, control alternating current and voltage, filter out unwanted electrical signals, and other functions. The company serves industrial, computing, automotive, consumer, telecommunications, power supplies, military and aerospace, and medical end markets. Vishay Intertechnology, Inc. was incorporated in 1962 and is headquartered in Malvern, Pennsylvania.
