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: Transient event duration must be < 1% of total lifetime of the part.
Note 3: Guaranteed by long term current density limitations.
Note 4: The LTC3634 is tested under pulsed load conditions such that
T J ≈ T A . The LTC3634E is guaranteed to meet specified performance
from 0°C to 85°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
LTC3634I is guaranteed to meet specifications over the –40°C to 125°C
operating junction temperature range. The LTC3634H is guaranteed
over the –40°C to 150°C operating junction temperature range and the
LTC3634MP is tested and guaranteed over the –55°C to 150°C operating
junction temperature range. High junction temperatures degrade operating
lifetimes; operating lifetime is derated for junction temperatures greater
than 125°C. Note that the maximum ambient temperature consistent with
these specifications is determined by specific operating conditions in
conjunction with board layout, the rated package thermal impedance and
other environmental factors.
Note 5: The junction temperature (T J , in °C) is calculated from the ambient
temperature (T A , in °C), package thermal impedance ( θ JA , in °C/W), and
power dissipation (P D , in Watts) according to the formula: T J = T A + P D ? θ JA .
Note 6: Output voltage settings above 3V are not optimized for controlled
on-time operation. For designs that set output voltages above 3V, please
refer to the Applications Information section for information on device
operation outside the optimized range.
Note 7: Dynamic supply current is higher due to the internal gate charge
being delivered at the switching frequency.
Note 8: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 150°C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
