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:
INTV

cannot be externally driven. No additional components or
loading is allowed on this pin.
Note 3:
The LT8364E is guaranteed to meet performance specifications
from 0°C to 125°C junction temperature. Specifications over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LT8364I is guaranteed over the full –40°C to 125°C operating junction
temperature range. The LT8364H is guaranteed over the full –40°C to
150°C operating junction temperature range.
Note 4:
The IC includes overtemperature protection that is intended to
protect the device during overload conditions. Junction temperature will
exceed 150°C when overtemperature protection is active. Continuous
operation above the specified maximum operating junction temperature
will reduce lifetime.
Note 5:
For SYNC/MODE inputs required to select modes of operation see
the Pin Functions and Applications Information sections.
Note 6:
The IC is tested in a Boost converter configuration with the output
