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 LTC3543E is guaranteed to meet performance speci?cations
from 0°C to 85°C. Speci?cations over the –40°C to 85°C operating
temperature ranges are assured by design, characterization and
correlation with statistical process controls.
