VIPer35 - Quasi-resonant high performance off line high voltage converter

General Description

VIPER35 is a high voltage converter, which smartly integrates an 800 V rugged power MOSFET with a quasi-resonant current mode PWM control.

This IC meets severe energy saving standards as it has very low consumption and operates in burst mode under light load conditions.

Key Features

  • 800 V avalanche-rugged power MOSFET allowing ultra wide range input VAC to be achieved.
  • Embedded HV start-up and senseFET.
  • Built-in soft-start.
  • Quasi-resonant current mode PWM controller with drain current limit (IDlim).
  • Multifunction ZCD pin:.
  • Zero-current detection.
  • OCP threshold (IDlim) setup.
  • Output OVP (auto-restart).
  • Feed-forward compensation.
  • Support isolated flyback topology with optocoupler.
