Note 1:
Stresses beyond those listed under Absolute Maximum Ratings to 125°C operating junction temperature range are assured by design, may cause permanent damage to the device. Exposure to any Absolute characterization and correlation with statistical process controls. The Maximum Rating condition for extended periods may affect device LT3741I is guaranteed to meet performance specifications over the –40°C reliability and lifetime. to 125°C operating junction temperature range.
Note 2:
The LT3741E is guaranteed to meet performance specifications
Note 3:
The minimum on, off, and nonoverlap times are guaranteed by from 0°C to 125°C junction temperature. Specifications over the –40°C design and are not tested.
