            InnoSwitch3-AQ Switcher ICs
                    Power Integrations' AEC-Q100 certified InnoSwitch3-AQ supports 30 V to 925 V input voltage
    

Power Integrations' constant voltage (CV) regulated InnoSwitch3-AQ switcher ICs achieve up to 90% efficiency across the load range and consume less than 15 mW under no-load conditions. Output power is up to 20 W at +85°C ambient temperature and 400 V_DC input for the 900 V family.

The devices incorporate a multi-mode quasi-resonant (QR)/CCM/DCM flyback controller, 900 V switch, and Power Integrations’ high-speed FluxLink™ communications link that enables accurate regulation in the compact InSOP-24D package and provides reinforced isolation up to 5,500 m altitude.

InnoSwitch3-AQ ICs operate down to 30 V_DC, enabling automotive designers to use the part in emergency power supply applications. They also include multiple protection features for automotive applications, including input overvoltage and undervoltage protection, output overvoltage and overcurrent limiting, and overtemperature shutdown.
