AC/DC offline switch, 300 KHz, 50W, DIL-8

OFF-line primary switch

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.
