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: Absolute Maximum Voltage at V
nonrepetitive 1 second transients.
Note 3: The LT3663E is guaranteed to meet performance specifi cations
from 0°C to 125°C. Specifi cations over the –40°C to 125°C operating
temperature range are assured by design, characterization, and
correlation with statistical process controls. The LT3663I specifi cations

lifetimes. Operating lifetime is derated at junction temperatures greater
than 125°C.
