Note 1:
Stresses beyond those listed under Absolute Maximum Ratings LT3048I is guaranteed over the full –40°C to 125°C operating junction may cause permanent damage to the device. Exposure to any Absolute temperature range. High junction temperatures degrade operating Maximum Rating condition for extended periods may affect device lifetimes. Operating lifetime is derated at junction temperatures greater reliability and lifetime. than 125°C.
Note 2:
The LT3048E is guaranteed to meet performance specifications
Note 3:
Current limit guaranteed by design and/or correlation to static test. from 0°C to 125°C junction temperature. Specifications over the –40°C Slope compensation reduces current limit at higher duty cycle. to 125°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls.
