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 LTC3113 is tested under pulsed load conditions such that
T
J
≈ T
A
. The LTC3113E is guaranteed to meet performance specifications
from 0°C to 85°C junction temperature. Specifications over the
–40°C to 125°C operating temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3113I is guaranteed to meet performance specifications over the
–40°C to 125°C operating junction temperature range.

Note 3:
This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. The maximum
rated junction temperature will be exceeded when the protection is active.
Continuous operation above the specified absolute maximum operating
junction temperature may impair device reliability or permanently damage
the device.
Note 4:
Voltage transients on the switch pins beyond the DC limit specified
in the absolute maximum ratings are non-disruptive to normal operation
when using good layout practices, as shown on the demo board or
described in the data sheet and application notes.
