    DESCRIPTION
    The
    TPS61040/41
    converter dedicated for small to medium LCD bias
    supply and white LED backlight supplies. The device
    is ideal to generate output voltages up to 28 V from a
    dual cell NiMH/NiCd or a single cell Li-Ion battery.
    The part can also be used to generate standard
    3.3-V/5-V to 12-V power conversions.
    APPLICATIONS
    LCD Bias Supply
    White-LED Supply for LCD Backlights
    Digital Still Camera
    PDAs, Organizers, and Handheld PCs
    Cellular Phones
    Internet Audio Player
    Standard 3.3-V/5-V to 12-V Conversion

    LOW-POWER DC/DC BOOST CONVERTER IN SOT-23 AND SON PACKAGES
    is
    a
    high-frequency
    boost
    The
    frequency up to 1 MHz. This allows the use of small
    external components using ceramic as well as
    tantalum output capacitors. Together with the thin
    SON package, the TPS61040/41 gives a very small
    overall solution size. The TPS61040 has an internal
    400 mA switch current limit, while the TPS61041 has
    a 250-mA switch current limit, offering lower output
    voltage ripple and allows the use of a smaller form
    factor inductor for lower power applications. The low
    quiescent current (typically 28
    μ
    A) together with an
    optimized control scheme, allows device operation at
    very high efficiencies over the entire load current
    range.
