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 LTC3566 family is guaranteed to meet performance
specifi cations from 0°C to 85°C. Specifi cations over the –40°C to 85°C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 3: The LTC3566 family includes overtemperature protection that is
intended to protect the device during momentary overload conditions.

Junction temperatures will exceed 125°C when overtemperature protection
is active. Continuous operation above the specifi ed maximum operating
junction temperature may impair device reliability.
