Description

General part information

VIPER53-E Series

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.Switching frequency up to 300kHzCurrent limitationCurrent mode control with adjustable limitationSoft start and shut-down controlAutomatic burst mode in standby condition ("Blue Angel" compliant )Undervoltage lockout with HysteresisHigh voltage start-up current sourceOvertemperature protectionOverload and short-circuit control
