ELECTRICAL CHARACTERISTICS
The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T A = 25 ° C. (Note 6)
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC4411E 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: T J is calculated from the ambient temperature T A and power
dissipation P D according to the following formula:
T J = T A + (P D ? 150 ° C/W)
The following table lists thermal resistance for several different board sizes
and copper areas. All measurements were taken in still air on 3/32" FR-4
board with the device mounted on topside.
Measured Thermal Resistance (2-Layer Board*)
Note 4: Quiescent current increases with load current, refer to plot of I QF
vs I LOAD .
Note 5: This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125 ° C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
Note 6: Current into a pin is positive and current out of a pin is negative.
All voltages are referenced to GND.
