Power Integrations InnoSwitch3 IC family

Power Integrations’ InnoSwitch3 IC family, with PowiGaN technology, is designed to deliver high-impact performance for demanding consumer and industrial applications while simultaneously reducing energy consumption. The IC family incorporates a high-voltage primary-side switch, the primary-side controller, a secondary-side controller for synchronous rectification and FluxLink technology that eliminates the need for an optocoupler.

As more applications increase their reliance on smart devices and power automation, demand for high-efficiency solutions with strong thermal performance is rising and GaN is quickly replacing silicon. PowiGaN is Power Integrations’ internally developed technology that allows its ICs to achieve 95% efficiency across the full load range and up to 100 W in enclosed adapter implementations without heatsinks. Claimed to be more efficient, more compact and lighter than silicon alternatives, the technology is suitable for diverse applications.
