ALTAIR05T-800:Off-line all-primary-sensing switching regulator

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
