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 LT3694E 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
LT3694I is guaranteed to meet performance specifications from –40°C to
125°C junction temperature.
Note 3: Current limit is guaranteed by design and/or correlation to static
test. Slope compensation reduces current limit at higher duty cycles.
Note 4: This is the minimum voltage across the boost capacitor needed to
guarantee full saturation of the internal power switch.
Note 5: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions.
Junction temperature will exceed the maximum operating range when
overtemperature protection is active. Continuous operation above the
specified maximum operating junction temperature may impair
device reliability.
Note 6: Absolute Maximum Voltage at VIN and EN/UVLO pins is 70V for
non-repetitive, 1 second transients and 36V for continuous operation.
Note 7: The LDO will function if the BIAS to DRV differential is not met,
but the base drive current will be drawn from VIN instead of BIAS.
Note 8: The PGOOD pin will pull low when the voltage on any of the three
FB pins is lower than the PGOOD threshold value.
Note 9: Positive currents flow into pins, negative currents flow out of pins.
Minimum and maximum values refer to absolute values.
