STMICROELECTRONICS VIPER53EDIP-E - AC/DC offline switch, 300 KHz, 50W, DIL-8

"OFF-line primary switch 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. Features • Switching frequency up to 300kHz • 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 • Integrated start-up current source • Overtemperature protection • Overload and short-circuit control • Overvoltage protection • In compliance with the 2002/95/EC European Directive"
