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 LTC4413 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.
Note 3: Quiescent current increases with diode current, refer to plot of I QF
vs I OUT .
Note 4: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions.
Overtemperature protection will become active at a junction temperature
greater than the maximum operating temperature. Continuous operation
above the speci?ed maximum operating junction temperature may impair
device reliability.
Note 5: This speci?cation is guaranteed by correlation to wafer-level
measurements.
Note 6: Unless otherwise speci?ed, current into a pin is positive and
current out of a pin is negative. All voltages referenced to GND.
Note 7: Guaranteed by design.
