VIPER53DIP-E AC/DC offline switch, 300 KHz, 50W, DIL-8

OFF-line primary switch

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 lockout with Hysteresis - HIgh voltage star-tup current source - Overtemperature protection - Overload and short-circuit control
