Overview

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.

  • 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
  • Frequency limit: - 136 kHz (L type), 225 kHz (H type)
  • Less than 30 mW @ 230 VAC in no-load condition
  • Brown-out set through resistor divider
  • Short-circuit protection (auto-restart)
