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: Based on long-term current density limitations. Assumes an
operating duty cycle of ≤ 10% under Absolute Maximum Conditions
for durations less than 10 seconds. Maximum current for continuous
operation is 150mA.
Note 3: The LTC3218E is guaranteed to meet performance speci?cations
from 0°C to 85°C. Speci?cations over the –40°C to 85°C ambient
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
