Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTM4600HVE is guaranteed to meet performance
specications from 0°C to 85°C. Specications over the –40°C to 85°C
operating temperature range are assured by design, characterization
and correlation with statistical process controls. The LTM4600HVI is
guaranteed and tested over the –40°C to 85°C temperature range.
Note 3: Refer to current de-rating curves and thermal application note.
