Description
The ALTAIR04-900 is a high voltage all-primarysensing 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.


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


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