The VIPER53ESPTR-E is an offline Primary Switch with a secondary power capability ranging up to 30W in wide range input voltage or 50W in single European voltage range and 40W in wide range input voltage or 65W in single European voltage range. It features overload and short-circuit events controlled by feedback monitoring and delayed device reset, efficient standby mode by enhanced pulse skipping and integrated start-up current source is disabled during normal operation to reduce the input power.
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 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 300 kHz CURRENT LIMITATION CURRENT MODE CONTROL WITH ADJUSTABLE LIMITATION SOFT START AND SHUT DOWN CONTROL AUTOMATIC BURST MODE IN STAND-BY CONDITION (“BLUE ANGEL” COMPLIANT) UNDERVOLTAGE LOCKOUT WITH HYSTERESIS HIGH VOLTAGE STARTUP CURRENT SOURCE OVERTEMPERATURE PROTECTION OVERLOAD AND SHORT-CIRCUIT CONTROL
