1 pcs : VIPER317LDTR - AC/DC Converters Energy Saving Off-line High volt Converter

VIPer31 High Voltage Converter STMicroelectronics VIPer31 High Voltage Converter integrates an 800V avalanche rugged power MOSFET with PWM current-mode control, in a compact SO-16 package. The 800V breakdown allows an extended input voltage range and reduces the size of the DRAIN snubber circuit. The VIPer31 offers very low power consumption and operates in pulse frequency modulation at light load, enabling it to meet the most stringent energy-saving standards. Overvoltage and Undervoltage protections with separate and settable intervention thresholds are available at OVP and UVP pins respectively. UVP can also be used as a disabling input for the entire SMPS, with ultra-low residual input power consumption. Integrated HV startup, sense FET, error amplifier, and an oscillator with frequency jitter allow a complete application to be designed with a minimum component count.
