    should be inserted in series with the TOVL pin.\


Description

The VIPer53-E combines an enhanced current mode PWM controller with a high voltage MDMesh Power Mosfet in the same package.

VIPer53-E 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, VIPer53-E has 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
