The InnoSwitch3-AQ Series from Power Integrations are AEC-Q100-Qualified Flyback DC-DC Converters that are designed for automotive applications. These converters convert an input voltage of 30-1200 V to an output voltage of 30-800 V. They deliver an output power of up to 100 W and have an efficiency of less than 95%. These converters incorporate multi-mode valley switching DCM (discontinuous-conduction mode)/ CCM (continuous-conduction mode) flyback controller, 750 V, 900 V or 1700 V switch and secondary-side sensing. They include an Integrated FluxLink feedback link that provides reinforced isolation. These ASIL-D-compliant converters consume less than 15 mW of no-load input power making them highly energy-efficient.

These EN IEC 60747-17-approved converters benefit from advanced protection and safety features such as auto-restart response for output overvoltage and over-current faults, accurate programmable output over-current threshold and programmable input undervoltage. They have IATF16949 certification at their fabrication, assembly, and testing sites, making them compliant with the automotive industry's quality management standards. These converters provide reinforced isolation in accordance with IEC60664-1 standards and are designed to withstand isolation voltages greater than 4000 VRMS. They are designed with excellent noise immunity, enabling them to meet Class "A" performance criteria for the EN61000-4 suite of standards. These RoHS-compliant converters are available in a surface-mount package that measures 10.80 x 9.40 x 1.6 mm and is ideal for power supplies for automotive subsystems such as the emergency power supply (EPS), traction inverter, high-voltage to low-voltage DC-DC converters, battery management system, on-board charger, and 12 V system standby.
