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.
