VIPER53-E中文资料固定频率离线转换器数据手册ST规格书

描述 Description

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.
