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 LTC4413-1/LTC4413-2 are guaranteed to meet performance
specications from 0°C to 85°C. Specications over the –40°C to
85°C ambient 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
IQF vs IOUT.
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 specied maximum operating junction temperature may impair
device reliability.
Note 5: Specication is guaranteed by correlation to wafer-level
measurements.
Note 6: Unless otherwise specied, current into a pin is positive and
current out of a pin is negative. All voltages referenced to GND.
