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 amplifier.
