VIPER31 - Energy saving offline high voltage converter

Datasheet Summary

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

  • ~ AC DIN RIN GND VCC OVP DRAIN VIPER31 FB.
