Beschreibung

ALTAIR04-900 is a high-voltage all-primary-sensing switcher intended for 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.

Eigenschaften

  • Primary side constant voltage operations with no optocoupler
  • Adjustable and main-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
  • SO16 package

Typische Anwendungen

  • SMPS for energy metering
  • AC-DC adapters
  • Auxiliary power supplies for 3-phase input industrial systems
