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 LT3651 is tested under pulse loaded conditions such that
TJ = TA. The LT3651E is guaranteed to meet performance specifications
from 0°C to 85°C junction temperature. Specifications over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LT3651I is guaranteed over the full –40°C to 125°C operating junction
temperature range. 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 θJA
where
θJA (in °C/W) is the package thermal impedance.
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 specified absolute maximum operating
junction temperature may impair device reliability or permanently damage
the device.
