LT3653
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C; VIN = 12V, VBOOST = 17V, VSW = 0V, RILIM = 33.2k, unless otherwise noted.

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 3: Absolute Maximum Voltage at V 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 2: The LT3653E is guaranteed to meet performance specifications
from 0°C to 125°C. Specifications over the –40°C to 125°C operating
temperature range are assured by design, characterization, and correlation
with statistical process controls. The LT3653I specifications are
guaranteed over the full –40°C to 125°C temperature range. High junction
temperatures degrade operating lifetimes. Operating lifetime is derated at
junction temperatures greater than 125°C.
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 specified maximum operating junction temperature may impair device
reliability.
