Power Integrations announced that shipments of the groundbreaking InnoSwitch family of ICs have surpassed one billion units. Launched in 2014, the InnoSwitch family was the first to incorporate Power Integrations’ innovative FluxLink communication technology, which provides highly accurate secondary-side control without the need for an optocoupler.

InnoSwitch ICs, including the InnoSwitch3 family which launched in 2017, support a diverse range of power-supply applications including USB PD chargers, consumer electronics, PCs, displays, servers, appliances, industrial devices and automotive. The InnoSwitch product range has expanded to include a wide range of variants.

InnoSwitch devices incorporate a range of silicon transistor options from 650 V to 900 V, or Power Integrations’ PowiGaN 750 V gallium-nitride (GaN) switch technology, which enables power delivery up to 100 W at 95% efficiency without a heatsink.

Commenting on the billion-unit milestone, Power Integrations’ president and CEO Balu Balakrishnan said: “The InnoSwitch family set a new standard in power-conversion technology and hailed a paradigm shift in power-supply design. The expensive, complicated method of combining a primary-side controller and associated MOSFETs with a synchronous rectification controller has given way to a more highly integrated architecture that is simple, elegant, more reliable and more efficient. We are delighted by the market’s response to InnoSwitch ICs and proud to have shipped more than one billion units.”
