LTC3406B-1.2
ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC3406BE-1.2 is guaranteed to meet performance
specifications from 0 ° C to 70 ° C. Specifications over the –40 ° C to 85 ° C
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
Note 4: Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
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.
dissipation P D according to the following formula:
LTC3406B-1.2: T J = T A + (P D )(250 ° C/W)
