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.
