    LED7706TR

    LED driver with boost regulator, 6-rows 30 mA, for LCD panels backlight

    Parameters
    Input Voltage Min Volt4.5
    Input Voltage Max Volt36.0
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeTape And Reel
    RoHs compliantEcopack2
    GradeIndustrial
    Package NameQFN-24L
    Description

    The LED7706 consists of a high efficiency monolithic boost converter and six controlled current generators (rows) specifically designed to supply LEDs arrays used in the backlighting of LCD panels. The device can manage an output voltage up to 36 V (i.e. 10 white LEDs per row).The generators can be...
