VIPER53EDIP E VIPER53EDIPE 497 6172 5 ND 49761725ND 497-6172-5
VIPER53EDIP-E General 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 8package 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.
