Power Integrations announced the production release of the InnoSwitch™3-AQ, an AEC-Q100-qualified flyback switcher with integrated 750 V MOSFET and secondary-side sensing. The newly qualified device family targets automotive EV applications, such as traction inverter, OBC (on-board charger), EMS (energy management DC/DC bus converters) and BMS (battery management systems).

The InnoSwitch3-AQ uses Power Integrations’ high-speed FluxLink™ coupling to achieve ±3% accuracy for combined line and load regulation while eliminating both dedicated isolated transformer sense-windings and optocouplers. FluxLink technology maintains output voltage regulation even under the transient stress test, which is particularly challenging for PSR-based implementations (more info, graphic: Business Wire).
