    Quad DC/DC Converter
    for Triple Output TFT Supply
    Plus LED Driver U FEATURES DESCRIPTIO ■ The LT®1942 is a highly integrated quad switching regulator designed to provide all necessary power supply
    functions for TFT displays, including the white LED
    backlight driver. The TFT supply incorporates two boost
    and one inverting DC/DC converters. The TFT supply
    output voltages are independently set, unlike charge
    pump solutions which have many limitations. Power
    sequencing for the TFT supply is built into the part and is
    user programmable. ■
