LT3496



3496ff

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: The LT3496E 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

LT3496I is guaranteed over the full –40°C to 125°C operating junction

temperature range. The LT3496H is guaranteed over the full –40°C to

150°C operating junction temperature range. High junction temperatures

degrade operating lifetimes. Operating lifetime is derated at junction

temperatures greater than 125°C.

nonrepetitive 1 second transients, and 30V for continuous operation.

Note 5: Gate turn-on/turn-off delay is measured from 50% level of PWM

voltage to 90% level of gate on/off voltage.

Note 6: The LT3496 includes overtemperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature will exceed the maximum operating junction temperature

when overtemperature protection is active. Continuous operating above

the specified maximum operating junction temperature may impair device

reliability.
