ELECTRICAL CHARACTERISTICS

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 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 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 specified maximum operating junction temperature may impair device

reliability.
