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.

Features ■ Switching frequency up to 300kHz
■ Current limitation
■ Current mode control with adjustable limitation
■ Soft start and shut-down control
■ Automatic burst mode in standby condition (“Blue Angel“ compliant )
■ Undervoltage lockoutwith Hysteresis
■ HIgh voltage star-tup current source
■ Overtemperature protection
■ Overload and short-circuit control
