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 LT3653E is guaranteed to meet performance speci?cations
from 0°C to 125°C. Speci?cations over the –40°C to 125°C operating
temperature range are assured by design, characterization, and correlation
with statistical process controls. The LT3653I speci?cations are
guaranteed over the full –40°C to 125°C temperature range. High junction
temperatures degrade operating lifetimes. Operating lifetime is derated at
Note 3: Absolute Maximum Voltage at V IN pin is 60V for non-repetitive
1 second transients.
Note 4: Switch Peak Current Limit guaranteed by design and/or correlation
to static test.
Note 5: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed the maximum operating junction temperature
when overtemperature protection is active. Continuous operation above
the speci?ed maximum operating junction temperature may impair device
reliability.
junction temperatures greater than 125°C.
