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 LTM4611 is tested under pulsed load conditions such that

Specifications over the full –40°C to 125°C operating junction temperature
range are assured by design, characterization and correlation with
statistical process controls. The LTM4611I is guaranteed to meet
specifications over the full –40°C to 125°C operating junction temperature
range. 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 resistance and
other environmental factors.
