VIPER53  DIP8  original

Features ■ Switching frequency up to 300kHz ■ Current limitation ■ Current mode control with adjustable limitation ■ Soft start and shut-down control ■ Automatic burst mode in standby condition (“Blue Angel“ compliant ) ■ Undervoltage lockout with Hysteresis ■ HIgh voltage star-tup current source ■ Overtemperature protection ■ Overload and short-circuit control

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
