    Note 1: Stresses beyond those listed under Absolute Maximum Ratings
    may cause permanent damage to the device. Exposure to any Absolute
    Maximum Rating condition for extended periods may affect device
    reliability and lifetime.
    Note 2: The LTC3859 is tested under pulsed load conditions such that
    TJ ≈ TA. The LTC3859E is guaranteed to meet specications from
    0°C to 85°C junction temperature. Specications over the –40°C to
    125°C operating junction temperature range are assured by design,
    characterization and correlation with statistical process controls. The
    LTC3859I is guaranteed over the full –40°C to 125°C operating junction
    temperature range. Note that the maximum ambient temperature
    consistent with these specications is determined by specic operating
    conditions in conjunction with board layout, the rated package thermal
    impedance and other environmental factors. The junction temperature
    (TJ in °C) is calculated from the ambient temperature (TA in °C) and power
    dissipation (PD, in Watts) according to the formula TJ = TA + (PD 
    qJA),
    where
    qJA = 34°C/W for the QFN package and qJA = 25°C/W for the TSSOP
    package.
    Note 3: This IC includes overtemperature protection that is intended to
    protect the device during momentary overload conditions. The maximum
    rated junction temperature will be exceeded when this protection is active.
    Continuous operation above the specied absolute maximum operating
    junction temperature may impair device reliability or permanently damage
    the device.
    Note 4: The LTC3859 is tested in a feedback loop that servos VITH1,2,3 to a
    specied voltage and measures the resultant VFB1,2,3. The specication at
    85°C is not tested in production. This specication is assured by design,
    characterization and correlation to production testing at 125°C.
    Note 5: Dynamic supply current is higher due to the gate charge being
    delivered at the switching frequency. See Applications information.
    Note 6: Rise and fall times are measured using 10% and 90% levels. Delay
    times are measured using 50% levels.
    Note 7: See Minimum On-Time Considerations in the Applications
    Information section.
