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
