ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LTC4413 is guaranteed to meet performance specifications
from 0
°
C to 70
°
C. Specifications 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 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 specified maximum operating junction temperature may impair
device reliability.
Note 5:
This specification is guaranteed by correlation to wafer-level
measurements.
Note 6:
Unless otherwise specified, current into a pin is positive and
current out of a pin is negative. All voltages referenced to GND.
