Redesigned Electric Vehicles now boast AEC-Q100 certification for 900V components
Power Integrations Announces Availability of InnoSwitch3-AQ Flyback Switcher IC Family for Electric Vehicle Applications
Power Integrations has announced the launch of its InnoSwitch3-AQ flyback switcher IC family, designed specifically for electric vehicle (EV) inverter, battery management, and climate control applications. The new ICs provide plenty of voltage headroom and meet the stringent requirements for qualification set by the Automotive Electronics Council.
The InnoSwitch3-AQ family, rated at 900 V, offers output power of up to 20 W at 85 °C ambient temperature and 400 VDC input. For 400 VDC designs, additional circuitry may be omitted. The ICs are priced at $2 in volume product quantities.
Both designs employ Power Integrations' StackFET technology. The devices incorporate a multi-mode Quasi-Resonant (QR) / CCM / DCM flyback controller, a 900 V switch, and Power Integrations' high-speed FluxLink communications link.
The InnoSwitch3-AQ family combines primary and secondary controllers, safety-rated feedback circuitry, and allows for accurate output voltage regulation. The ICs also include multiple protection features for automotive applications such as input over-voltage and under-voltage protection, output over-voltage and over-current limiting, and over-temperature shutdown.
The ICs operate down to 30 VDC, enabling automotive designers to use the device in traction inverter emergency power supply applications. A new design reference, DER-889Q, is available for a 15 W power supply that supports 30 VDC to 1200 VDC input and 12 V / 1.25 A output. Another design reference, DER-859Q, describes the operation of InnoSwitch3-AQ in 800 V bus applications delivering up to 30 W.
The InnoSwitch3-AQ switcher ICs achieve up to 90% efficiency across the load range and consume less than 15 mW under no-load conditions. For further inquiries, contact a Power Integrations sales representative or one of the company's authorized worldwide distributors: Digikey, Farnell, Mouser, and RS Components. More information can be found on the Power Integrations website (www.power.com).
