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 LT3581E is guaranteed to meet performance specifications
from 0°C to 125°C. Specifications over the –40°C to 125°C junction
temperature range are assured by design, characterization and correlation
with statistical process controls. The LT3581I is guaranteed over the full
–40°C to 125°C operating junction temperature range. The LT3581H is
guaranteed over the full –40°C to 150°C operating junction temperature
range. Operating lifetime is derated at junction temperatures greater than
125°C.
Note 3: Current limit guaranteed by design and/or correlation to static test.
Note 4: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 150°C when overtemperature protection is active.
Continuous operation over the specified maximum operating junction
temperature may impair device reliability.
