Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LTC3426 is guaranteed to meet performance specifications
from 0
°
C to 70
°
C. Specifications over the –40
°
C to 85
°
C operating
temperature are assured by design, characterization and correlation with
statistical process controls.
Note 3:
This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125
°
C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
