Note 2: The LT3653E is guaranteed to meet performance specifi cations Note 5: This IC includes overtemperature protection that is intended from 0°C to 125°C. Specifi cations over the –40°C to 125°C operating to protect the device during momentary overload conditions. Junction temperature range are assured by design, characterization, and correlation temperature will exceed the maximum operating junction temperature with statistical process controls. The LT3653I specifi cations are when overtemperature protection is active. Continuous operation above guaranteed over the full –40°C to 125°C temperature range. High junction the specifi ed maximum operating junction temperature may impair device temperatures degrade operating lifetimes. Operating lifetime is derated at reliability. junction temperatures greater than 125°C. 3653f 3
