ELECTRICAL CHARACTERISTICS
The l denotes the speci?cations which apply over the –40°C to 85°C
temperature rang e, otherwise speci?cations are at T A = 25°C, V IN = 12V. Per typical application (front page) con?guration.

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 LTM4600E is guaranteed to meet performance speci?cations
from 0°C to 85°C. Speci?cations over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls. The LTM4600I is guaranteed over the
–40°C to 85°C temperature range.
Note 3: Test assumes current derating versus temperature.
Note 4: Guaranteed by correlation.
