Power Integrations designs and markets analog and mixed-signal integrated circuits for high-voltage power conversion applications, enabling the conversion of electricity from high-voltage sources to specified forms—typically AC to DC or vice versa with adjusted voltage levels and regulated output. The company's core product lines include AC-DC power supplies for consumer devices and appliances, high-voltage gate drivers for industrial motors and renewable-energy systems, and motor-driver ICs for brushless DC motors in appliances and equipment; it differentiates through system-level integration that combines transistors, drivers, and control circuitry into single products, reducing design complexity and improving efficiency. Power Integrations operates on a fabless manufacturing model, working with foundries and subcontractors, and generates revenue through direct sales to OEMs and merchant power-supply manufacturers alongside indirect sales through distributors, serving communications, computing, consumer, and industrial end markets worldwide.
