VIPER319 - Energy saving offline high voltage converter

Download the VIPER319 datasheet PDF (VIPER31 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for energy saving offline high voltage converter.

Description

The VIPER31 device is a high-voltage converter that smartly integrates an 800 V avalanche rugged power MOSFET with PWM current-mode control..

The 800 V breakdown allows extended input voltage range to be applied, as well as to reduce the size of the DRAIN snubber circuit.

Features

  • 800 V avalanche-rugged power MOSFET to cover ultra-wide VAC input range.
  • Embedded HV startup and sense FET.
  • Current mode PWM controller.
  • Drain current limit protection (OCP):.
  • 850 mA (VIPER318) ~ AC DIN RIN.
  • 990 mA (VIPER319) VCC OVP DRAIN VIPER31.
  • Wide supply voltage range: 4.5 V to 30 V FB.
