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 LTC3562E 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 control.
Note 3: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions.
Overtemperature protection is active when junction temperature exceeds
the maximum operating junction temperature. Continuous operation above
the speci?ed maximum operating junction temperature may result in
device degradation or failure.
Note 4: The serial port is tested at rated operating frequency. Timing
parameters are tested and/or guaranteed by design.
