  • The ALTAIR05T-800 is a high-voltage all-primary sensing switcher intended to operate directly from the rectified mains with minimum external parts. It combines a low voltage, high performance PWM controller chip and an 800 V avalanche rugged power section in the same package.

    Key Features

    • Constant voltage and constant current output regulation (CV/CC) with no optocoupler
    • Tight regulation also during heavy load transients
    • 800 V avalanche rugged internal power section
    • Quasi-resonant (QR) operation
    • Low standby power consumption
    • Automatic self-supply
    • Input-voltage feedforward for mains-independent CC regulation
    • Output cable drop compensation
    • SO16N package
