    VIPerPlus family: Peak power fixed frequency high voltage converter

    Parameters
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeTube
    RoHs compliantEcopack2
    GradeIndustrial
    Package NameSO-16
    Description

    The device is a high-voltage converter that smartly integrates an 800 V rugged power MOSFET with PWM current-mode control. The power MOSFET allows a very high input Vac to be applied, just limited from its breakdown voltage. This IC is capable of meeting more stringent energy-saving standards as it...

    Key features
    Key features
    • 800 V avalanche-rugged power MOSFET allowing ultra wide range input Vac to be achieved
    • Embedded HV start-up and sense FET
    • PWM current-mode controller
    • OCP with selectable threshold (IDlim) and 2nd OCP with higher value (IDMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode
    • 30 mW no-load consumption at 230 Vac
    • Two operating frequencies:
      • 60 kHz (L type) or 115 kHz (H type)
    • Jittered frequency reduces the EMI
    • Extra power timer (EPT) blanks the overload current for few seconds
    • Output overvoltage protection with tight tolerance and digital noise filter
    • Soft-start reduces the stress during startup and increases IC lifetime
    • Automatic restart after a fault condition
    • Thermal shutdown increases system reliability and IC lifetime
