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
– Efficient standby mode by enhanced pulse
– Primary regulation or secondary loop failure
OFF LINE PRIMARY SWITCH
feedback monitoring and delayed device reset.
