VIPER319 Datasheet Energy Saving Offline High Voltage Converter

Manufacturer: STMicroelectronics

Overview: VIPER31 Datasheet Energy saving offline high voltage converter.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.

The IC can meet the most stringent energy-saving standards as it has very low consumption and operates in pulse frequency modulation at light load.

Key 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.
