Description

The VIPer53E 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 and 40W in wide range input voltage, or 65W in single European voltage range and PowerSO-10 package, with the following benefits:

– Overload and short-circuit events controlled by feedback monitoring and delayed device reset;
– Efficient standby mode by enhanced pulse skipping.
– Integrated start-up current source is disabled during normal operation to reduce the input power.
