Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Current limit guaranteed by design and/or correlation to static test. may cause permanent damage to the device. Exposure to any Absolute Slope compensation reduces current limit at higher duty cycle. Maximum Rating condition for extended periods may affect device
Note 4:
This IC includes overtemperature protection that is intended reliability and lifetime. to protect the device during momentary overload conditions. Junction
Note 2:
The LT8616E is guaranteed to meet performance specifications temperature will exceed the maximum operating junction temperature from 0°C to 125°C junction temperature. Specifications over the –40°C when overtemperature protection is active. Continuous operation above to 125°C operating junction temperature range are assured by design, the specified maximum operating junction temperature may impair device characterization and correlation with statistical process controls. The reliability. See High Temperature Considerations section. LT8616I is guaranteed over the full –40°C to 125°C operating junction temperature range. The LT8616H is guaranteed over the full –40°C to 150°C operating junction temperature range. 8616fa 4 For more information www.linear.com/LT8616
