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.

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
