Organization, Consolidation and Presentation of Financial Statements [Abstract]
THE COMPANY [Text Block]	THE COMPANY: Power Integrations, Inc. (“Power Integrations” or the “Company”), incorporated in California on March 25, 1988, and reincorporated in Delaware in December 1997, designs, develops, manufactures and markets analog and mixed-signal integrated circuits (ICs) and other electronic components and circuitry used in high-voltage power conversion. The Company’s products are used in power converters that convert electricity from a high-voltage source (typically 48 volts or higher) to the type of power required for a specified downstream use. A large percentage of the Company’s products are ICs used in AC-DC power supplies, which convert the high-voltage AC from a wall outlet to the low-voltage DC required by most electronic devices. Power supplies incorporating the Company’s products are used with all manner of electronic products including mobile phones, computing and networking equipment, appliances, electronic utility meters, power tools, industrial controls, lighting applications that utilize light-emitting diodes (LEDs), and “smart-home,” or “internet of things” applications such as networked thermostats, power strips and other building-automation and security devices. The Company also offers high-voltage gate drivers – either standalone ICs or circuit boards containing ICs, electrical isolation components and other circuitry – used to operate high-voltage switches such as insulated-gate bipolar transistors (IGBTs). These combinations of switches and drivers are used for power conversion in high-power applications (i.e., power levels ranging from a few kilowatts up to one gigawatt) such as industrial motors, solar- and wind-power systems, electric vehicles and high-voltage DC transmission systems.
