VIPER53ESPTR-E Datasheet PDF - ST Microelectronics

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.

● Automatic burst mode in standby condition

● Undervoltage lockout with hysteresis

● Integrated start-up current source

● Over temperature protection

● Overload and short-circuit control

● Overvoltage protection

● 300kHz Switching frequency

● In compliance with the 2002/95/EC European directive
