Product overview

Description

The ALTAIR04-900 is a high voltage all-primary-sensing switcher, operating directly from the rectified mains with minimum external parts. It combines a high-performance low voltage PWM controller chip and a 900 V avalanche-rugged power section in the same package.
  • All features

    • Optoless primary side constant voltage operations
    • Adjustable and mains-independent maximum output current for safe operations during overload/short-circuit conditions
    • 900 V avalanche-rugged internal power section
    • Quasi-resonant valley switching operation
    • Low standby consumption
    • Overcurrent protection against transformer saturation and secondary diode short-circuit
    • SO16N package
