ELECTRICAL CHARACTERISTICS The

denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VIN = 12V, EN/UVLO = 12V unless otherwise noted.

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: INTVCC cannot be externally driven. No additional components or

loading is allowed on this pin.

Note 3: The LT8365E 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

LT8365J and the LT8365H are 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

voltage programmed for 24V.
