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
