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...

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):710 mA (VIPER317)850 mA (VIPER318)990 mA (VIPER319)
  • Wide supply voltage range: 4.5 V to 30 V< 20 mW @ 230 V< 430 mW @ 230 V
  • Jittered switching frequency reduces the EMI filter cost:30 kHz ± 7% (type X)60 kHz ± 7% (type L)132 kHz ±7% (type H)
  • Embedded E/A with 1.2 V reference
  • Built-in soft-start for improved system reliability
  • Protections with automatic restart:overload/short-circuit (OLP) thermal shutdownovervoltage
  • Protections without automatic restart:pulse-skip protection to avoid flux runawayundervoltage/disable max. duty cycle
