VIPER53SP E VIPER53SPE 497 6805 5 ND 49768055ND 497-6805-5
VIPER53SP-E General 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. Block diagram
