VIPER53-E Fixed frequency off line converter
The VIPer53-E combines an enhanced current mode PWM controller with a high voltage MDMesh Power Mosfet in the same package. Typical applications cover offline power supplies with a secondary power capability ranging up to 30W in wide range input voltage, or 50W in single European voltage range and DIP-8 package, with the following benefits:
- Overload and short circuit controlled by feedback monitoring and delayed device reset.
- Efficient standby mode by enhanced pulse skipping.
- Primary regulation or secondary loop failure protection through high gain error amplifie
技术特性
