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 the device
reliability and lifetime.
Note 2: Positive currents ow into pins, negative currents ow out of pins.
Minimum and maximum values refer to absolute values.
Note 3: Absolute maximum voltage at VIN and RUN/SS pins is 60V for
nonrepetitive 1 second transients, and 36V for continuous operation.
Note 4: The LT3695E regulators are guaranteed to meet performance
specications from 0°C to 125°C junction temperature. Specications
over the –40°C to 125°C operating junction temperature range are
assured by design, characterization and correlation with statistical process
controls. The LT3695I regulators are guaranteed over the full –40°C to
125°C operating junction temperature range. The LT3695H regulators are
guaranteed over the full –40°C to 150°C operating junction temperature
range.
Note 5: These ICs include overtemperature protection that is intended
to protect the devices during momentary overload conditions. Junction
temperature will exceed the maximum operating junction temperature
when overtemperature protection is active. Continuous operation above
the specied maximum operating junction temperature may impair device
reliability.
Note 6: This is the voltage necessary to keep the internal bias circuitry in
regulation.
Note 7: Current limit guaranteed by design and/or correlation to static test.
Slope compensation reduces current limit at higher duty cycles.
Note 8: This is the minimum voltage across the boost capacitor needed to
guarantee full saturation of the switch.
