VIPER53DIP General Description

The VIPer53 combines in the same package an enhanced current mode PWM controller with a high voltage MDMesh Power Mosfet. Typical applications cover off line 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.
