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 LTC3589/LTC3589-1 are tested under pulsed load conditions
such that T
specifications 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 LTC3589I/LTC3589I-1 are guaranteed over the –40°C to 125°C
operating junction temperature range and the LTC3589H/LTC3589H-1 are
guaranteed over the full –40°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. The

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 3: The LTC3589/LTC3589-1 include 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
temperature may impair device reliability.
