    VIPER319HCTR

    Energy Saving Off-line High Voltage Converter

    Parameters
    Operating Temp Min Celsius-40.0
    Operating Temp Max Celsius125.0
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeTape And Reel
    RoHs compliantEcopack3
    GradeIndustrial
    Package NameSO-16
    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...

    Key features
    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 VAC in no-load;
      • < 430 mW @ 230 VAC, 25 0mW output load
    • 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 shutdown
      • overvoltage
    • Protections without automatic restart:
      • pulse-skip protection to avoid flux runaway
      • undervoltage/disable
      • max. duty cycle
