Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
The IC includes overtemperature protection that is intended to may cause permanent damage to the device. Exposure to any Absolute protect the device during overload conditions. Junction temperature will Maximum Rating condition for extended periods may affect device exceed 150°C when overtemperature protection is active. Continuous reliability and lifetime. operation above the specified maximum operating junction temperature
Note 2:
INTV will reduce lifetime. CC cannot be externally driven. No additional components or loading is allowed on this pin.
Note 5:
For SYNC/MODE inputs required to select modes of operation see
Note 3:
The LT8361E is guaranteed to meet performance specifications the Pin Functions and Applications Information sections. from 0°C to 125°C junction temperature. Specifications over the –40°C
