    Products Detail

    VIPER38LD Description


    The VIPER38LD is a high-voltage converter that smartly integrates an 800 V rugged power MOSFET with PWM current-mode control. The power MOSFET VIPER38LD allows a very high input Vac to be applied, just limited by its breakdown voltage. This IC is capable of meeting more stringent energy-saving standards as it has very low consumption and operates in burst mode under light load. The VIPER38LD features an adjustable extra power timer (EPT) that enables the IC to sustain overload conditions for a few seconds.



    VIPER38LD 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 a selectable threshold (IDlim) and 2nd

    OCP with a 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 a few seconds



    VIPER38LD Applications


    Auxiliary power supply for consumer and home equipment

    Power supply for energy meters and data concentrators

    Adapters

    Automotive 

    Hybrid, electric & powertrain systems 

    Industrial 

    Aerospace & Defense 

    Enterprise systems 

    Enterprise machine
