VIPER53DIP-E Datasheet PDF - ST Microelectronics

●The VIPER53DIP-E is an Offline Primary Switch combines an enhanced current mode PWM controller with a high voltage MDMesh Power MOSFET. 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. It features overload and short circuit controlled by feedback monitoring and delayed device reset, efficient standby mode by enhanced pulse skipping and primary regulation or secondary loop failure protection through high gain error amplifier.
